if i could go absolutely anywhere i would go to Thailand to the full moon party i hear its really really bad but also a really great experience to have .
It all depends. If I had a way of getting back quickly, I would enjoy going to some far away star system that has planets. (This is only if this chance to go anywhere was by teleportation.)
Hum, it's really hard to choose only one destination... I would go to Sweden because it's a beautiful and peacefull country (and an Heavy Metal country !^^)
hmm maybe dubai just for the simple fact all the nice and exotic cars you see there driving around... and maybe the fact that they got some crazy advanced resorts and junk
