It was a life long dream to go to Hawaii and it was everything I hoped it would be. My wife and kid and I went last September.
We rented a jeep from National, and it came in handy a few times on the beach. We also rented a condo from
VBRO which was great - nice and close to the beach. We started off with a dinner cruise, and over the next week we did Pearl Habor, snorkeling, swimming with dolphins, and kayaking. For most events I booked through
Hawaii Activities - their website looks crappy but they have live people at the other end that call you in the event there are problems. One of the favorite things I did was the
Bishop Museum .
I basically planned an event or two a day, and then we spent the rest of the time shopping or at the beach. Lots of time at the beach...
