Heather and Ben love piñatas (as do we!) and had one at their intimate cactus garden wedding. But sometimes you want your goodie-filled paper animals to contain a little something something for the adults. So they filled it with mini plastic liquor bottles and chocolate liqueurs. I would imagine there was a line to take a whack.
This idea would rock for a child-free wedding. Or, if there are kids at your wedding, just have a completely separate pinata for them.
