Mrs. Jabber and I are going to Maui in a few weeks for our 10th anniversary (sans kids!

). Since this is our first time to Maui, I thought I'd solicit the experts for your best & favorite things to do or see on Maui. We're big on activities like hiking, biking, drinking, eating, etc, but anything interesting or off the beaten path would be great. Thanks in advance!

ps. I guess I should also ask for things specifically NOT to do, overblown, overpriced, or just a downright waste of time.
