We stayed in Wailea when we were in Maui. I liked staying in that area as opposed to Kapalua which gets more rain. My favorite part of the trip was the helicopter ride. What I saw was so beautiful that I cried. We also liked snorkeling. You can rent snorkeling equipment, but I would advise you to take at least your own snorkel so you don't have to put something in your mouth that has been in someone else's. We drove around the island to get a feel for the different geography on the island. I also enjoyed watching the surfers.
We spent most of our time just relaxing at the beach and the pool, getting cooled off by being sprayed with Evian water by the pool attendants. It was very luxurious (Four Seasons). Sally Field had the cabana next to ours. It was kind of exciting to be that close to a famous actress. No one bothered her, and I'm sure she appreciated that.
No remarkable food. We did a luau (gotta do that once, I guess). It was interesting but didn't float my boat. I liked the Lahaina Grill (just like the funkiness of that area), but it gets mixed reviews.
