I half-assed my summer party last year, and didn't do it at all the year before. I'm already thinking about it for this year though, and I can't even tell you how excited I am to do it.
We were talking about summer parties at work, and someone suggested getting a rental hot tub. Yes, they have such a thing, and they show up with it on a trailer and that's that! That would certainly be a fun and tropical addition to the luau. Better start getting sexy if I decide to do that.
Especially at parties. I have a friend who got his used for like two grand from a divorced chick who just wanted rid of it. And I must say - it's a babe magnet. I was hanging out last night at a house in front of a wood fireplace with a bottle of wine and then into a hot tub.... honestly I thought to myself, "This guy could be Jeffrey Dahmer and I'd be falling for him right now..." LOL. Having your own is the way to go.
