Hi, Daniel!
Oh, sweet
Disney Aulani. There is absolutely no end to the beauty that exists in Hawaii, and Aulani is a huge part of that in Kapolei. Activities at the resort vary, and while there has always been something going on for fourth of July, I can't tell you for sure what you might be in for. In years past, there has been some poolside fun and a party exclusively for teens, but the best is the fireworks. Snag a spot on the beach, and you can watch the display, which is put on by the Ko Olina Resort Association for all resort guests.
The resort tends to be bustling on Fourth of July, so if you plan to enjoy any of the resort dining experiences, I highly recommend that you book in advance.
Makahiki, the resort buffet, features some of the freshest local flavors with an international flair. They also have a great character breakfast. For something a bit nicer, you may want to try
'Ama'Ama Contemporary Island Cooking, where you can watch the sunset.
Have a wonderful vacation!
Anna
