不哭不哭. Sometimes, relaxing on the beach, sipping coffee, reading a good book, people watching, sunset watching (the list goes on) is just as fun. If I were, I'd alternate between driving around the island sight seeing and then the next day relaxing on the beach. Try snorkeling in different places (as the snorkeling rental places and they usually know good snorkeling beaches). Haunama Bay will take you 1/2 a day, 1/2 a day at Pearl Harbor, Diamond Head 1/2 a day, visiting some botanical gardens, a couple of hours riding the Atlantis submarine, sunset dinner cruise, taking a scuba diving lesson. This is a very good chance to take a nice relaxing vacation. There is plenty to do and sometimes doing nothing is just as nice or even better than an action packed vacation schedule.
