We booked the Norwegian Dawn from Boston to Bermuda at the last minute. The ship had just come in from Dry Dock so we thought it would be nice to cruise on a nearly new ship and also we liked the idea of cruising from Boston.
In addition Concierge-level on the Dawn was cheaper that a regular room on Disney.
We had previously only been on Disney cruises so I thought I would compare the two as it was information I wanted when booking the cruise.
