Partyyy....!?

im having a party in february at a hotel for boys and girls (sleepover..) and idk what to do should we swim because the hotel has an indoor pool...but what games could we play...by the way were looking at about 30 - 40 people and we cant play truth or dare or at least not until the parents are sleep and idk what to eat... anything but pizza. My party has to be awesome because this is the year every one has the bat/bar mitzvahs and im not jewish sooo i want my party to be cool. I have a budget of about 400-500 dollars not including the price of the hotel. But what should i give out. Are sweatpants only for bat/ bar mitzvahs??? I really need help any info is greattt.!
