I'm kidnapping my boyfriend and taking him to Honolulu for Valentine's Day. He's never been there before and has no idea we are going. We arrive Wednesday February 13 at 5:30 pm and depart Sunday February 17 at about 6:30 pm. So, we have 4 days to fill with siteseeing. Musts include Pearl Harbor (1/2 day) and hiking Diamond Head (1/2 day). Any suggestions for the other days? Perhaps a Circle Island Tour by limousine?
