It's a little unconventional to take a whole roll of TP, but I wouldn't hesitate to do it if I was, y'know, in a gastrointestinal situation that required it.
I don't think any hotel in this world would have an issue with that. Please bro, take a roll. You need two? Here...just in case...
Taking the hotel room's skunky yoga mat? I'll take a hard pass on that one.
