A friend of mine will be renting a hotel room for a night this month for his birthday party. It's going to be a small gathering of just about 4 of us. I offered to help plan for some activities for but I'm kind of at a loss. The last birthday party I went to was when I was a kid so all I remember is stuff like Princess parties or piñatas LOL. I'm also not the party type so I don't have much experience with it period.

Does anyone have an idea of what a couple of grown adults can do for fun on a birthday? So far I think we can probably go swimming at the hotel and hit up a local karaoke bar. But I don't know what we can do in the room itself which is where most of the party will happen.
