Very funny...not sure if that's supposed to be a joke or not, but quite amusing! I think I'll copy and paste that to the invites...especially the canapes!

Frankly, at a birthday party, I DO expect the hostess to entertain and supervise my child. I would be most perturbed if I picked my (under 10) child up and the child said, "Suzie's mom told us to amuse ourselves and then went off to have a nap."
I'm not sure how many times I have to post this, but I'm only concerned about the kids safety around the pool. Personally, there's only a few people I would trust to watch my kid in the water, so I would NOT let my daughter go to a pool party without me or her dad, but obviously that's just me. It's not like I'm going to lounging on a beach chair with a frozen drink and instruct the kids to run along so they don't block my sun.
I appreciate everyone's advice, but I can see this is going no where fast! Thanks for all the responses and I'll be sure to update when we decide what to do and let everyone know how it goes! Other than that, I think I'm over the party planning for now...I need to get through Christmas!

It's always good to be explicit about your expectations where birthday parties are concerned. If you like the invite and you think your guests will be amused, by all means use it!
