We did this about 3 years ago. Carnival had tickets aboard ship for $19 and if you didn't use them you could get a refund. Nice view from top. Bar was OK then. We had a couple of beers and walked around. There was some sort of a trampoline/bungee bounce thing that you could do. They harnessed you ina bungee harness and then put you on a trampoline. Looked like fun but us oldies :-) thought better. Enjoy your cruise. Another note: last time we were there (2010) there was along line waiting to go up.
