Taking bikes into the hotel...

I've never had any problems. I usually use the side entrance. I definitely do not ask--just do it. Don't use hotel towels to clean your chain or anything!

I've taken my bikes into plenty of hotels. The only place I got some dirty looks was at a Marriott in downtown Chicago. I was on one of the upper floors, so was having to take the bike up and down via the elevator.

I've washed my bike in the shower at a Super 8 after a particularly wet and gritty day.

Used TP and shampoo to clean up afterward, didn't leave any stains.
