I also just got the move up offer prompt for our March 18 cruise. Currently have a midship prime veranda. Minimum offer is $150 pp. for upgrade. I don't like the idea of not knowing where my stateroom will be, but Blu dining and spa amenities would be nice. Since it is spring break week, the ship will likely be full and I am thinking it may even be hard to get in the thermal spa spaces. Still thinking about it!
