Been using the hotels.com app for six years. I travel 200 plus days a year. Use it for the free night every ten days. Problem is the customer service will hang up on you in the middle of a call (just happened) app does NOT REFLECT THE HOTEL AVAILABILITY! If you check on the app a lot of times it shows no availability and there is! This summer multiple screw ups. Unreliable, horrible and rude customer service. The 800 number is awful! Wasted several hours of my time for the last time! Don't rely on them!
