I was travelling with a family of 3 and our age group is late 20's (me) and my parents in early and mid 50's. We are not very experienced cruisers and we have only tried HAL Oosterdam before to Alaska. So I guess this review is more like a comparison of which cruise ship is better in what areas.
Embarkation:
Right from the beginning, I got the impression that the Disney's staffs were not as well trained as HAL's. The man who checked us in was not as friendly as HAL's and we had a slow process, as one of our passport was not stamped by the US custom. When we cruised with HAL's, we felt people are generally very welcoming, but our first impression with Disney's staff was like seeing any other people in big cities, such as NYC.
Great and huge balcony, lots of closets and storage space, lots of vibration at night, not a quiet location as it is right below deck 11 (public deck). I saw people throwing bread on my balcony when they were trying to feed birds.
