I thought the decor was tacky, but who cares, you'll met a ton of awsome ppl and you'll have a blast. Go to the Rex after dinner, that was the best part for me and i think everyone whos been on the Paradise will agree.
I went on the Paradise last year to the same ports that your going to. I loved the ship and thought that the decor was beautiful..the have those little fiber lights everywhere always changing colors...There is one thing you should tell your parents and be careful of..On the day that you visit San Juan..you will have to go through customs before getting off of the ship, BE IN LINE AT LEAST ONE HOUR EARLY!!!! Or else, you'll be standing in a line with 2,000 other people waiting in line for customs..and then trying to get off. Seriously, they only use 3-5 immigration officers for 2,000 passengers, and you don't want to have to wait in line for hours..also..they made everyone stay on the ship until everyone had gone through immigration...so..get yours over and done with so that you aren't in the mass of people waiting on the Rex Disco Level (dunno the level name) to go through customs..and then you can wait for everyone else to go through over breakfast or what not..have a blast..if you have any questions..feel free to ask!
