Anyone have any suggestions?!

Anyone have any suggestions?

I am having a luau in October and would like a Hawaiian-themed, delicious alcoholic signature drink or punch to serve my guests rather than having to have someone bartend.

Any suggestions, with recipes to go with it?

OK, secret family recipe here...hope they're not on yahoo answers:

2 oranges
2 lemons
2 limes
1 small-medium box of frozen strawberries (depends on how much you like them)
1 can of lime ade
1/2 a .750 of vodka (you can get the flavored kind if you want)
Ice
Get a one gallon jug, like the kind used for tea. Put in the lime-ade. Cut up the fruit, squeeze the juice into the jug then layer the ice, and fruit chunks as you wish. Add the vodka in the end. Wrap a towel around the jug and take turns shaking it until the towel sticks to the jug. Everybody works for the drink and everyone will love it!
