Attire: for the 4 of us, I purchased matching Hawaiian outfits from the Disney catalog last summer. My husband and son wore the matching Hawaiian shirts with white shorts and my daughter and I wore the same print matching sundresses. We received many compliments on our matching Hawaiian outfits!  At our welcome table, each child received a Hawaiian lei, Hawaiian flower hair clip for girls and bright color sunglasses for the boys. We also had nametags available for all where they could look up their name in Hawaiian and write it on their nametag. The Hawaiian name binder was well received and the kids enjoyed looking up their name. I found the names on alohafriends website and put the print out of all names into a clear binder. I took some loose Hawaiian petals and decorated the exterior of the binder with the flowers so looked very festive and pretty. I put a label on the binder that said, look up your Hawaiian name.  Music: purchased several Hawaiian music and party music CD's to add to the atmosphere.
