I checked a couple of prices based on 2 passengers:
* NCL 7-night Caribbean on the Escape for Sept 9, 2017 =
$2495.34 and it includes the Specialty Dining Plan (I think it's 3 specialty restaurants for a 7-night cruise) and Ultimate Beverage Package (unlimited soda and alcohol) in a Family Balcony Room.
* When I checked
RCL I see Oasis Sept 10, 2017 as $2220.22 + $151.04 soda =
$2371.26 because there is a BOGO on the second passenger (-$675). It's a Superior Ocean View with Balcony room.
* DCL Fantasy Sep 9, 2017 Category 7A Veranda is
$3430.02.
Maybe we're not checking the same categories, but I see DCL as being $1000 more than NCL and RCL. My husband and I talked about it the other day and would absolutely LOVE to sail DCL again. We sail for the destinations and to be together as a family. We can do that on any line. Plus we thought the food in the specialty restaurants on NCL was amazing!
Edit - You beat me to it
