It is generally accepted that RCI offer the best facilities for children - especially the new largest ones - Freedom, Liberty and Independence.
Cruised on the Freedom with our 7 year ld daughter and she just loved it. It is a magnificent vessel, new and bright and sparlky clean. Loads of activities for the kids to keep them busy all day and night. They have a great pirate's parade where the kids dress up, quite appropriate for the carribbean.
