I spent a week in Saipan in the Navy and loved it. I've had the opportunity to travel all over Asia and if you like a relaxed tropical environment Saipan is the place. Some shops cater only to Asians and don't speak any English, that was a little annoying after a while but there’s plenty to do. If you go get your diving license first and to blue grotto. The night dives are the best since the sea turtles sleep there at night.
