It is very freeing to not have to walk around with a wallet or think about anything or do anything. Want food, ask for it. Want a drink, ask for it. Your complicated decision is whether to go to the pool or beach and even if you 17 that decision up somehow, you just walk a minute or two and you have corrected it. As someone mentioned, teh food is usually pretty mediocre, but that's a decent enough tradeoff. I don't have to travel to get nice food, so I don't mind mediocre food for a little while. Definitely not something I would care to do all the time and not in place of actually going and experiencing new things, but it's a nice experience every few years.
Got to do an all inclusive between jobs one time, and it was glorious. Probably won't experience a lack of stress like that again unless and until I retire.
