You know I considered Ireland or England myself, but ultimately I realized all I'd be doing there is the same thing I do here when not playing STO or working. Hit the pub until the we-hours then repeat the next day off. Only real difference would be the setting when I walked outside and the pleasant change of all the really nice imported beer I drink here would be cheap domestic beer there *drools two dollar Guinness*. Also the ditch I curled up in after staggering out or getting kicked out would be slightly different, possibly even containing sheep.
Would really rot to be kicked out of a country that two generations ago housed one side of my family, that said probably wise if I avoid it.
Iceland (once they get all the volcanic ash business cleaned up) or Japan. Specifically, I'm not sure what I'd do but either plave would offer tons to do and I would plan out everything in advance once I knew I was going. I'd also want at least one guest to accompany me.
