The first time i went to something like that, as an adult, it was SRD (State Recognition Days) with my TOPS (Take Off Pounds Sensibly) chapter. We went four people to a room, two people to a bed.
I did enjoy the goofing around and snacking while in the room - but - along with snoring - it takes me a long time to get "situated comfortably" once I do go to bed. Sharing a room is tolerable - but I definitely prefer to have my own bed. (Poor DH - sometimes I feel so sorry for him with me flopping around like a freshly caught fish in the bottom of a boat.)
After being married 57 years, we usually don't take it (too) personally if/when one of us gets up and goes to the couch.
