We are going on a 7 night cruise to Mexico from LA on the disney wonder. This is our first cruise. We have twin daughters 20 months old who are extremely active and loud. We would appreciate your suggestions to the following questions and any other advise is also welcome! 1. Early dinner or late dinner? what time does the late dinner end? Our kids usually go to bed by 8:30 pm and we have been assigned the late dinner. Is the sit down dinner even an option for us? 2. Will be there enough to do for two non-potty trained kids? How should we plan activities and what would you recommend? Many thanks!
