That is a crowd of people, for sure.
Back in the late 80s and early 90s we took three cruises. Two out of Miami into the Caribbean, and one out of LA to Encinada. We enjoyed the Caribbean ones the most.
If you have not been on one before, you are in for a treat. man they will feed you like a king and you will eat so much until you can't eat anymore. A lot of fun and they were very relaxing for us.
