We completed are second voyage on the Magic in April 2016. We had sailed previously on the Magic in 2012, prior to the drydock improvements. We sailed with a teen and preteen.
First - I tend to like the new mega ships with all of the bells and whistles. Disney Magic is an exception to that however. Our voyage was full with over 1,000 kids, but it never felt crowded. From experience on other ships it can be difficult to get an elevator on the first try. Oddly, although the Magic has small elevators, we never had an issue.
Reimagined - Disney did a spectacular job with the drydock. Our first voyage on the Magic was very mediocre, with the food experiences at times less than that. No longer. The renovations made to the buffet restaurant (called Cabanas now) on the pool deck are spot on. The space is larger and better organized. The food choices and quality were very good. I would state that their version of the buffet restaurant now exceeds those on RCCL and Celebrity (2 lines we often cruise with).
Great
