If you like long line ups you will love the embarkation and disembarkation process for the Disney cruises. We have taken many cruises and our experience with Disney was the worst.
The advantages of the cruise are the many activities for kids: water sports, beach activities, mini-golf, shows, music etc. Also, the staff are very good with children.
But the negatives are substantial. The ship was very crowded and line-ups were common for many activities. Because of the number of people the ship was noisy and somewhat chaotic.
Cabin was fine, nothing special, just standard
