Although most of Aunty's Beach House is free (you only need to pay for meals, if needed, and lunch and dinner cost $10 each), there are a few offerings that parents can opt in for at an additional cost. These interactive activities showcase the wonders of Hawaii and include souvenir keepsakes. For example, your kids can play traditional Hawaiian children's games with none other than Moana or take a field trip for an up-close encounter with tropical fish.
