I went to the Bahamas on Royal Carribean. Had an absolute blast! I would agree with not purchasing the ship excursions. There will be plenty of local things to do when you port. I wouldn't even try to sneak alcohol on the ship. No point in ruining your whole trip if you get caught. The drink prices weren't THAT bad, pretty much the same prices you would pay at a club/bar. Just pick a bar on the boat, make friends with a bartender and perhaps you'll get a hook up. I can't suggest anywhere to go other than the Bahamas, but that was a blast. I'm pretty sure anywhere you go, you'll enjoy it. Have fun if you decide to go on one!!
