If you can sneak away... go to Feeme Nu for titty's by the convention center (trust me). At night, drive Tantlus in Honolulu. It overlooks that part of the island and is where drifting started in Hawaii in the 80's before 240's became popular. I would recommend taking a drive around the island. Driving on Hawaii Kai/Sand Island is amazing. If the waves are up, it's worth a trip to the North Shore to take it all in. On the North Shore, there is a shrimp place up by Kahuku. Hike Diamond Head and see if you can sneak into the Stairway to Heaven in Kaneohe. If its during the day to start things off, the Mai Tai Bar has amazing chopped steak and cheap pitchers of beer for Hawaii. The island is best when you just roam around, eat plate lunches, and enjoy the scenery/beautiful women.
As others have mentioned, a helicopter ride in Kauai is something you will never forget. The only problem with this time of the year, is the rain.
The Ugly:
Here is a safety warning. If some says "hey Haole" and not in a friendly way, that basically means what the fuck is your problem white boy in local slang. Also, if you try to pick up a hooker in Honolulu near China Town, they likely have a dick. I would recommend you don't go out to Waianae. Folks are usually nice out there, but there are still shit heads that start shit with random people from the mainland who are loud and don't respect the land or locals.
