After cruising more than 20 times on most other lines, my husband and I (retired, in our late 60's) finally bit the bullet and tried a Disney cruise last January. We were impressed with several things we think Disney did very well. The embarkation and especially debarkation was flawless. We have NEVER gotten up from a breakfast table before and been told to "just leave the ship." There were NO lines, waiting, fumbling--just empty gangways--a real pleasure.
The rotational dining was fun and a well managed concept. We enjoyed our adult table for 8 and excellent servers who all stayed together for the whole cruise. Food was good and reflected theme of each restaurant. We didn't spring for Palo additional fee dining.
Castaway Cay was a nice retreat and even started the day with a 5K run for my husband. (We had been at WDW for the marathon weekend preceding cruise so this was another opportunity for a completion medal). Picnic lunch was good and everything but liquor was included for day.
