Hey thanks for the quick responses. I love how homebrewtalk forums has a wealth of knowledge from other helpful DIYers. I think I am going to go with 2 handles(probably vodka of the gods from trader joes) as this is going to be for my daughter's second birthday and I don't want the other mommies and daddies getting too hammered.
I think the novelty of fountain cocktails will be appreciated by non beer drinkers and should help the beer last longer. The billdozer sounds pretty good and I might have to mix up a keg next time we have a party when my daughter is doing a sleepover with grandma. Thanks again for the help. The party is Saturday so I will posts follow up of the recipe I end up using and how it turns out.
