Oki is off the wall on some things, boring as hell on others. I always pickled my liver there. I'm a Squid though, thats what we do there. White Beach is a hole in the wall. Kadina is pretty nice however. The base is huge. Plus you are close to Naha, the party district. If I could give you advice.. Travel as much a you can while you are here. Really. You are close to tons of stuff... Hong Kong, Korea, Oz, Mainland... See it. Its a blast!
Never know, I may be heading that way some day. Seems we are trooping there more.
