March 2017 has been out since October 2015. Prices go up as the cruise sells. March is spring break time but Easter 2017 is April 16th so that might help with the March cruises. For the best price, I would book sooner than later.
Book as soon as you can!!! It is amazing how much they go up from opening day. Right now March 28th, 2016 4 night on the Dream $4749. March 27th, 2017 4 night on the Dream $2706. WOW!
I'd book sooner rather than later. The cruise category I have booked for March 2017 has had three price increases from when I made my reservation back in November 2015.
