I went to the hotel gym for the first time in my adult life on a week long business trip last year. Felt awkward the first day,but it was so nice waking up fresh and early, working out for an hr, back to the room for a shower, nice healthy breakfast and off to work..you know..like a responsible adult..
I even went a few nights too because the weather sucked for sight seeing and the lobby bar was looking a bit tempting at that time in my sobriety.
