Carnival Splendor has a covered pool so even if it's rainning the pool is still open. Plus the Splendor is the newst ship sailing Mexican Riviera. For me the choice was between the Carnival Splendor and Royal Caribbean the Mariner of the seas. Since the Splendor was cheaper I went with that. The May 2, 2010 cruise was surprising inexpensive. My room is a 4E with Early Saver (non refundable) booking it was $509 per person not including taxes and port charges. Check out the web cam of the Splendor pool. The have the sliding roof open today because it's sunny. PS. I loved that movie Pineapple Express.
