if your Hotels.com account was left logged in on a computer or elsewhere, then someone else could have inadvertently searched hotels using your account, and they would also show up on the same account on your phone.
Do you recognize what area the hotels were in?
Do you know anyone who may have visited that area?
If the search was not carried out on your phone, and was not carried out on another device using your hotels.com account, then it may just be a glitch in the hotels.com app
Hi, just checking in on your question. How did things work out for you?
