We have been on 2 Carnival and 1 Royal Caribbean cruises. There are pros and cons for both. Our second Carnival cruise was on a very old ship after our first one on a brand new ship. Not a good choice on our part. The ship was small and very smelly. Although it was a nice cruise the ship left alot to me desired. We decided to try Royal Caribbean and the ship was wonderful, however we did not enjoy the cruise director and activities near as much. For that reason we have come back to Carnival and are going out on the Spirit in December. We travel with several couples and we all have the same feelings. We are in our late 40's & early 50's but enjoy having a great time. I would sail Royal Caribbean again but prefer Carnival.
