Which Island??
In early December, I will be visiting a friend doing a post-doc in Honolulu. I'll be in Hawaii for two weeks total (arrive 1-Dec and leave 15-Dec). We plan to travel to another island for about 5 days (over the middle weekend of my trip).
We are graduate students (well, she'll be a post-doc) in our late 20s. Lounging all day on the beach is not a high priority (and I can get lots of beaching in in Oahu). Relative low cost is better, but not the deciding factor. We'd be able to rent a car. It will be my first time in Hawaii and my friend will not likely have traveled to many of the islands (she's only starting her position in April).
With that in mind, could you suggest an island?
