Holiday to Hawaii in Aug 2013: Booked Attractions

So what are we planning on doing when we get there? We’ve done some research and have booked the following things already:

Pearl Harbor on Oahu – famous for the battle that triggered the US’ involvement in the Second World War. We are booked for the full tour including the USS Bowfin Submarine, USS Arizona Memorial, USS Missouri Battleship, Pacific Aviation Museum – we are both really looking forward to this
Luau on Maui – the Old Lahaina Luau is apparently the best dinner and traditional Hawaiian entertainment on the island, so you’ve got to take it all in haven’t you!
Snorkeling on Maui – we have booked with Suzzy Robinson of Maui Snorkel Tours – she has got really good feedback on TripAdvisor and we can’t do Hawaii without doing some sort of water based activity

That’s about all that’s booked at the mo. Thinking about a trek up the volcano on Big Island.
