In case you don't get to RV-ate in Maui, here's another suggestion to aviate over there:

Check out the Familiarization Flights section for details
Suggest renting a plain old C-172 with an instructor and going island hopping with one of their experienced instructors. It is expensive, but you don't get that kind of view from the cockpit windows everyday. Touring the coast near Haleakela, then over the town of Lahaina then over to the old leper colony on the island of Molokai and the wrecks near the island of Lanai are all nearby and worth the cost of admisssion.
I flew left seat, but made the instructor do all the boring work (communicate with Class C tower since he had all the freq's in his head) and I just sat back and flew wherever he told me. It was a memorable experience to fly out over the ocean, but within reasonable gliding distance of multiple islands. We had a blast. Wife took about 100 pix from the back seat and thoroughly enjoyed it.
Best vacation fun I ever had aside from taking my RV on vacation.
