Liz, first of all, welcome to the board! Since this site was started by Ngaire, who does not book with Crystal, you probably won't find much information about those ships. However, you will find many trying to lure you over to Radisson because of the value they provide vis a vis Crystal (at least what I find in my research)! But if you have questions about ports, there is a vast amount of experience on this board. Fire away with your questions!
