I recently spent a weekend in a hotel with a bunch of friends and colleagues. To help cut down on costs, some of us shared rooms.
I like reading before I go to sleep, but my room-mate was tired and went to sleep early. Since I didn't want to bother him with the lights, so I went looking for a different place to read. I discovered that my hotel had a "Great Room" with plenty of tables and chairs, arranged around a fireplace.
I would have been very comfortable reading in that room, as I might in my own living room, but I didn't quite feel like doing that since I wasn't sure if etiquette demanded being fully dressed in that kinda-public space.
Is it okay to walk around a hotel in pajamas/sleepwear?
If it makes a difference, this hotel was in America. But I'm also interested in more global answers, if the information is available.
