Invitation Idea Make invitations that look like surfboards. Use floral printed scrapbook paper and then glue a white strip down the center of the surfboard. On the back write the information for the party. Be sure to tell the guests to come in attire they can get wet in.
Decoration Ideas Decorate with flowers, paper lanterns, foliage and streamers. Set up some beach umbrellas especially over the food and craft areas. Make long garlands of flowers and put them down the center of tables as table runners. Tape grass skirts to the edge of tables. Play Hawaiian music in the background. Put Tiki torches in the ground.
Craft Ideas Have the kids make their own leis. Provide them with string, silk flowers and colorful straws cut into about one inch pieces. Show them how to alternate between the flowers and the straws.
Game Ideas Have a hula-hoop contest give the guest who can hula hoop the longest gets a prize. Have the kids divide into twos give each group a beach towel, and then have them pass a water balloon around. Turn on a sprinkler that shoots water up and have a limbo competition. Hold the pole over the sprinkler and guests have to go under the pole (make sure no one will trip on the hose).
Food Ideas Make fruit kabobs with tropical fruits such as pineapple and oranges. For a drink have smoothies. Serve in coconut cups with umbrellas. Make a cake that looks like the ocean or make a volcano cake (recipes for a volcano cake can easily be found online).
