We are going on our 1st DCL cruise in a few weeks on the Wonder. We were considering rebooking on board. But, then we saw a 13 night RC Explorer cruise that interested us. They have been on 5 (7 nights cruises). I am worried that a 13 night would be too long. Also, I am concerned that they might not find kids program fun after DCL. (They have enjoyed RCI in the past) They will be 11 and 9. Thanks for your thoughts.
