I've stayed in a lot of hotels (I'm 69) and this is the first time I was bitten by bed bugs. I'd attach a photo but I see no place to do that. We had to leave everything outside the apartment door until all of our clothing coould go into the dryer. There were three of us in the room and I was the only one bitten, luckily.
The hallways had an odd chemical amwell, and I assume that was bug spray.
