The short answer
The strongest code reported this month is MCHK100, worth $100 off qualifying bookings of $800 or more. Two independent deal trackers list it as working, with the most recent shopper reports from October 8, 2026. If your stay costs between $500 and $800, the code MCSG60 takes $60 off select bookings when you pay with a Mastercard, and shoppers reported it working on October 10, 2026. Keep in mind that both trackers note codes can stop working or change terms at any time, so it is worth pasting a code at checkout before assuming it applies.

A third deal appears on trackers without a fully confirmed code string: an 8 percent member deal valid until January 31, 2027. It shows recent shopper activity but did not meet our two-source rule for a published code, so we left the exact characters out rather than guess.
How to use a code at checkout
RetailMeNot walks through the standard steps and they match what shoppers describe on the trackers. Pick your destination, dates, and room first. Choose the Pay Now option rather than Pay at the Property, since coupon codes do not apply to pay-later bookings. On the payment page, click “Apply Coupon Code,” type the code exactly as shown, and hit Apply. Your total should adjust right away. If it does not, double check the spelling, the minimum spend, and whether the property is excluded.
One Key: the free rewards program that keeps paying
This is the part of Hotels.com most travelers underuse. One Key is free to join and covers Hotels.com, Expedia, and Vrbo under one account. Members earn 2 percent back in OneKeyCash on eligible hotels, vacation rentals, car rentals, cruises, and activities, with each dollar of OneKeyCash worth exactly one dollar toward a future booking. Flights earn far less at 0.2 percent. Status tiers change the math further: Silver members unlock 15 percent or more off select hotels, and Gold and Platinum members get 20 percent or more, plus bigger OneKeyCash bonuses at VIP Access properties. The earnings do not expire as long as you make an eligible booking or redeem rewards within 18 months.

Can you stack codes with rewards
Only one promo code goes on each booking. That part is firm. What you can combine is a promo code with member prices and OneKeyCash credit on the same reservation, which is how frequent travelers squeeze the most out of a single stay. One exception worth knowing: codes do not work when you pick Pay at the Property. Prepaid rates are the ones that accept discounts.
More ways to cut the price without a code
One Key members see member-only prices on hundreds of thousands of stays, often 10 percent or more below the guest rate, and these show up only after you sign in. The Hotels.com app sometimes carries exclusive coupons and mobile-only prices that never appear on desktop. Email signups bring deal alerts and occasional exclusive codes. Cashback sites list Hotels.com at up to 14 percent back through early January 2027, and that cashback can sit alongside a promo code. Before paying full price, try the price guarantee too: if you find the same room cheaper on another site before check-in, Hotels.com refunds the difference as OneKeyCash.
When discounts get deepest
Code volume rises around predictable moments. Black Friday and Cyber Monday are the big ones, with recent years bringing up to 30 percent off for One Key members across a sale week that now stretches into Travel Tuesday. Express Deals and last-minute deals run year round and can reach 50 to 60 percent off select properties. Spring travel season in March also brings heavy code activity as summer planners start booking.
FAQs
Do Hotels.com promo codes work on every hotel?
No. Most codes apply only to select properties and always require a prepaid rate. Check the offer terms before counting on the discount.
Why did my code not apply?
The usual causes are a wrongly typed code, a booking below the minimum spend, an excluded property, or selecting Pay at the Property. Prepaid bookings are the ones codes work on.
Is One Key really free?
Yes. Joining costs nothing and there is no fee to earn or use OneKeyCash.
Do OneKeyCash rewards expire?
They stay active as long as you make an eligible booking or redeem rewards at least once every 18 months.
Can I use a code together with member prices?
Yes. You cannot use two codes at once, but one code plus member pricing plus OneKeyCash on the same booking is allowed.
Do codes work with Pay at the Property bookings?
No. You need to choose the Pay Now option for a coupon code to apply.
