Anyone been on both ships? We did a 4night midship balcony room on Disney Dream. LOVED everything about this first cruise. We have a 13year old-did not use the kid clubs. How does Disney Dream compare with Harmony of the Seas? We aren't gamblers or drinkers. Is Harmony just as gorgeous as Disney Dream? Any chance there is less movement on these bigger ships? We did have some very noticable rocking two nights on our Dream sailing. Are formal nights and dressy clothes optional or mandatory on RCCL? How are the shows and entertainment? How is Coco Cay compared to Disney Castaway? Any input appreciated. Debating saving for another Disney cruise or trying Harmony. Disney was about $3100 for 4nights and Harmony is $2700 for 7.
