Thanks for all the suggestions...plans have changed. I went to target for cups, plates, etc and walked through the party section and was inspired. We are now having pirate golf at our house. Snacks will be fish & chips (goldfish and potato chips in the same bowl), peg legs (pretzels), pirate's booty, pirate's treasure (rolos and hershey kisses) and hopefully a pirate ship made out of a watermelon.
DH found a recipe for Pirate's Grog.
I bought eye patches and if the golfer wears one will golfing then they can take -1 from their score. If they hit their ball into Deadman's reef or Davy Jones' Locker then it's +1. We have written our Pirate Golf rules using "pirate" language.
