SWEETPEA -- Please don't let this person ruin your vacation!!
January 2008 we went to Hawai'i, took a cruise around the islands, and ended up in the Waikiki beach area for three days. There is so much to do and see on the island. Even just the idea of lying on the sand and vegging is appealing. Google "Waikiki Beach" and explore the possibilities. The trip to the USS Arizona is the greater part of a day and is not to be missed. It is a once in a lifetime experience to see this memorial. Also I believe the Polynesian Cultural Center is on the same island. That also is an all-day and evening experience and is great for kids and adults.
Most people only get one or two chances in their life to go to Hawai'i. Enjoy it for all it's worth!!
