We were at the Andaz a couple of months ago for our honeymoon, fantastic resort. pretty cool snorkeling right off the beach at the hotel. Morimotos is in the resort, wolf gang puck's at the 4 seasons was superb. The Lobster grilled cheese is a must while hanging out poolside for lunch.
Look into what the Andaz has to offer for airport pickup/drop offs and car use for guests, it might work out for you and you may not have to pay for a rental and save some bucks.
Any water activity you want to do, get up early for it, once noon hits the water starts getting way too choppy and only gets rougher throughout the day. The helicopter tour was pretty cool as well, take a light jacket, they're not pressurized so they get chilly in there.
