I had a very similar bait and switch / bathroom experience in the same hotel earlier this year.
The switch was still pretty hot, albeit heavily tattooed, so I didn't walk. However, her attitude was horrible and 30 minutes became 15 minutes then your time was up. I would have reviewed, but the profile disappeared the same day.
Also, she claimed to be from Belgium, but another girl came out of the bathroom after 15 minutes and they were not speaking either Flemish or French. Sounded like a Romance language, probably Romanian.
Lesson learned, next time I get B&S, I walk.
