I try to have a pool party every summer. I have a 18x36 foot in-ground pool with a real deep-end and diving board. The shallow end has a slide. I also have a trampoline so the nieces and nephews and my friends kids have allot to do. They love the spa also. Not a huge party but do get about 40 people at it. I've tapered it back allot also, one year I had it catered, cost me about $3000 now I ask everybody to bring a dish to pass and I do hot dogs, hamburgers and steaks on the grill. I also provide the drinks.
