Hello. Well, if you want a big ship for the Southern Carib, check out the Adventure of the Seas. She is 138,000 tons. She is in the class of ships, which is the biggest so far that RCCL has. She does a 7 day southern carib out of Puerto Rico through next feb and march. I guess there are alot of factors to consider. I do think the Brilliance is a good idea, the best of both worlds like sonny said. Good luck!
