Hotels.com Coupons for September 2025

Once you find the hotel that fits your itinerary, click “Reserve” to start the booking process. At checkout, choose “Pay Now” and enter your code in the “Apply a coupon code” box before confirming. If you are booking through the Hotels.com app, you will see an “Apply a coupon” option on the payment screen. 

Keep in mind that promo codes do not apply to vacation rentals or stays where payment is collected at the property.

The Hotels.com Deals page is one of the best spots to score serious savings. We’ve seen discounts of up to 40% on hotel stays, including nearly $500 off at the elegant Lombardy Hotel in New York City, $200 a night off a boutique stay in London, and plenty of Las Vegas escapes at 40% off at places like the Venetian, Hilton Grand, and Gold Coast Hotel and Casino.

Holiday weekends are often when the best deals pop up. This past Labor Day had some of the strongest discounts we’ve seen, and Black Friday is up next. We’ll update you with more info once those offers go live, so you can plan your next trip with a little extra room in the budget.

Sometimes waiting until the last minute actually works in your favor. Hotels.com has last-minute deals that can take 30% or more off your stay, which makes saying yes to a spur-of-the-moment trip feel a lot easier.

Here’s how it works. Hotels do not want empty rooms, so when they still have vacancies, they drop the rates on platforms like Hotels.com to fill them fast. And the savings can be seriously good. We spotted a two-night weekend stay at the gorgeous Planters Inn on Reynolds Square in Savannah go from $804 to $607. That is 20% off for a dreamy weekend in the South. We also came across a two-night stay at the Hotel Beacon in New York City for $1,141, down from $1,817. That is 37% off and a perfect excuse to plan a last-minute city break.

If you are the kind of traveler who likes to keep a bag half-packed, these deals are basically made for you.

Think of OneKey Rewards as your secret travel hack. The second you join (for free, by the way), you’ll start unlocking discounts on thousands of hotels.

From there, every trip you take adds up to rewards you can actually use. A weekend getaway earns a little, a big vacation earns a lot, and you can spend those rewards just like real cash on your next booking.

And since the program works across Hotels.com, Expedia, and Vrbo, every kind of trip counts—whether it’s a quick reset close to home or the bucket-list escape you’ve been dreaming about.

Ahead, we’ll break down exactly what you get with the program.

Unlock Instant Savings with Member Prices

The first perk kicks in right away. Member Prices give you 10% or more off over 100,000 hotels the second you sign up. It’s built-in savings you can count on every time you book. And as you move up the program’s tiers, those discounts climb too—up to 20% or more at the higher levels. Think of it as your quiet edge against the rising cost of chic city hotels and dreamy resort stays.

Earn and Spend Rewards That Feel Like Cash

Every booking earns you OneKeyCash™, a rewards currency that actually works like cash. You’ll get 2% back on hotels, vacation rentals, car rentals, and activities, plus 0.2% back on flights. Then, when you’re ready to book your next trip, you can spend OneKeyCash dollar-for-dollar on eligible bookings. No blackout dates, no fine print—just straightforward savings you can put toward a better room, a longer stay, or maybe that splurge-worthy dinner. And as long as you keep traveling (at least one booking every 18 months), your rewards never expire.

Climb the Tiers for Bigger Perks

Your status in OneKey is based on “trip elements,” which are simply credits for what you book. Each hotel night counts as one element, and each car rental day counts as another. The more elements you collect in a year, the higher your tier and the better the perks.

Here’s the breakdown:

—Blue: Everyone starts here. You’ll unlock member prices with at least 10% off thousands of hotels and start earning rewards on every booking.

—Silver: With five trip elements, you get 15% or more off select hotels, priority customer support, and bonus rewards at VIP Access properties.

—Gold: At 15 elements, you’ll unlock 20% or more off top stays, complimentary room upgrades when available, and bigger reward bonuses.

—Platinum: With 30 or more elements in a year, you’ll get the steepest discounts, the highest OneKeyCash bonuses, and dedicated VIP support.

Why It’s Worth It

OneKey keeps things simple. You join for free, start saving right away, and earn rewards on almost everything you book. The best part is those perks add up fast, which gives you the kind of savings that free up your budget for little luxuries—like upgrading your room, adding an extra night, or finally splurging on a bottle of Dom Pérignon.

If Hotels.com is your go-to for booking stays, a One Key credit card can take your rewards game to the next level. Both cards come with serious sign-up bonuses, automatic status upgrades, and cashback you can actually use on future trips. 

Here’s the breakdown:

The OneKey Card

—Has no annual fee

—Earn $300 in OneKeyCash after spending $1,000 in the first three months

—Collect 3% in OneKeyCash on Hotels.com, plus gas, groceries, and dining

—Reach Gold status when you spend $15,000 in a year or Platinum at $30,000

The OneKey+ Card

—Has a $99 annual fee.

—Earn $400 in OneKeyCash after spending $3,000 in the first three months.

—Includes automatic Gold status, with Platinum unlocked after $30,000 in annual spending.

If you want to turn your hotel bookings (and even your grocery runs) into extra nights away, these cards make it easier to get there faster.

The Hotels.com app is one of the easiest ways to unlock extra savings. Some of the best deals are only available in the app, which means you will not see them if you are booking on the website.

The app also makes booking easier. You can compare hotels side by side, keep your loyalty points in one place, and confirm your stay in just a few taps before the deal disappears.

So whether you are mapping out a big annual getaway or pulling together a spontaneous weekend, the app helps you lock in the lowest rate—and leaves more in your budget for champagne toasts, spa treatments, or whatever “treat yourself” moment you have in mind.

Hotels.com does not hand out direct discounts for students, teachers, or military members, but that does not mean you are out of luck. A little detour through the right partners can unlock serious savings.

ID.me is the place to start. Military members, nurses, first responders, healthcare workers, government employees, teachers, and students can all verify their status and score around 8% off plus up to 2% cash back.

Students have even more options. Platforms like Student Beans and UNiDAYS regularly share Hotels.com promo codes, and the savings are no joke. Student Beans has offered up to 25% off, while UNiDAYS has gone as high as 40%. Just keep in mind that these deals sometimes come with restrictions on how often you can use them, so always check the fine print before you book.

Hotels.com makes it easy to book with confidence thanks to its Price Guarantee. If you find a cheaper rate for the same hotel and dates on another site, Hotels.com will match it. You do need to be a OneKey member to qualify, but since membership is free, it is an easy win. The difference shows up as OneKeyCash, which you can use toward future bookings.

The guarantee also applies to Hotels.com itself. If you book a room and later see a cheaper rate on the site, Hotels.com will rebook you at the lower price and refund the difference. With refundable reservations, you can cancel and rebook with no penalty. For nonrefundable stays, the lower-price difference is added to your account as OneKeyCash.

So whether you like to book early or double-check prices right before your trip, the Price Guarantee makes sure you never miss out on a better deal.

Discount codes are just one way to score a deal. If you really want to stretch your budget—and maybe spring for a little extra luxury—try a few of these insider tricks:

—Sort by price first. Switching your search from lowest to highest can reveal flash deals that disappear quickly.

—Think off-season. Paris in November, Cabo in May—popular destinations cost less (and feel less crowded) when you skip peak tourist months.

—Stay midweek. Tuesday and Wednesday nights often run cheaper than weekends, making them perfect for a quick escape.

—Play the points game. Even if another site is only a few dollars less, booking through Hotels.com helps you level up with OneKey. Higher status brings better perks and sometimes those dreamy free upgrades.

—Go all-in. Hotels.com’s all-inclusive listings can be a budget saver in destinations where food and drinks usually come with sky-high markups.
