Hawaii Tours?????

Does anyone have information on the tours you did or have booked in Hawaii? Good/bad and the ok? Price (was it worth the $$$$). Is it better to book in advance with TA or book when you get to the Islands? Any help?

Here are a few we are thinking about:

Waikiki
Pearl Harbor-Arizona Memorial City Tour

Maui
Old Lahaina Luau
Haleakala Sunrise Tour

Kauai
Kayak & Hidden Valley Falls Hike

Maui - I think
Road to Hanna?
Bike tour down the volcano?

Thanks

For the Pearl Harbor tour I think you just go there in the morning for tickets, no need to buy in advance (I think it was around $30pp when I asked the travel agent).

For the Old Lahaina Luau I would definitely book that in advance!! I probably will also book the Hyatt's Drums of the Pacific in advance too, since I've heard that its good.

The others you listed I haven't researched yet. But I just got my Hawaii entertainment book in the mail yesterday so I'm going to check out what coupons are in there (www.entertainment.com).
