16th birthday party help?!

So im turning 16 at the end of the month and im planning on having a hotel party with a couple of friends. Besides me there will be 2 guys and 2 girls invited. The guys will be leaving around 10. Some things im thinking about doing are swimming, movies, wii games, and maybe something like truth or dare if everyone else wants to. Besides that any suggestions or comments on anything else we could do or things ive mentioned that you don't think would be a good idea. any help is appreciated =]]
