We will be in Oahu for 10 days and staying in Waikiki. We definitely want to go see Pearl Harbor and we plan on island hopping at least 1 day, maybe 2. I really want to go to the Volcano National Park on the Big Island but we aren't sure what the other islands are known for activity wise. We bought our own snorkeling gear from Dick's Sporting Goods so that we can do our own thing with that when we are exploring. We've also heard a lot about a neat bike ride that goes down a mountain, I think it's on Maui?
I've been doing plenty of research, but I really wanted to hear from people who had been themselves. For those of you who have been or are planning to go, what have you done or are planning on doing? Also, is there anything that you think was overrated and/or not worth doing?
