Birthday Express and Shindigz also have many luau inspired items. I also know that the Dollar Tree carries quite a bit in the spring/summer months. Since it is a seasonal item at The Dollar Tree, I would check after Easter.
At our earlier luau, we made a rainbow/sun craft.
Games were fun and simple. We playes limbo with a pool noodle
Pass the coconut
Throw the ring on the flamingo.
I made a homemade version of this craft for our western/horse party. I cut a shape out of foam board attached it to a stake and then we threw a lasso made from a hula hoop and rope. For a luau, you could make a pineapple shape and use dollar store hula hoops.
At both parties, we had hula lessons. I found a CD with basic lessons in it, but I am sure steps can be found on the internet.
I also looked up the names of the girls on a word translator, and shared with them their Hawaiian names. They thought this was really cool.
At each party, I have all the party guests post with an item from the theme. At the first luau, the children posed with Stitch, and the second giant monkey.
I do not have pictures of the food. (this was before I knew I would have a party themed blog.. LOL) I served age appropriate foods at each party. At the 2 yr old party we served juice boxes, and simple food. At the 5 yr old party we had fruit skewers, potato chips, smoothies.
