Darlene, as much as I like CCL I have sailed on other lines in the past and will in the future. Varity is great and every line offers something differant. I still like CCL best but still will cruise on others.
I've been on four Carnival cruises and am about to go on a fifth... I think they're great fun! Be sure to read the reader reviews to get some really detailed accounts of what Carnival cruises are like.
