Hi - We just got off the 3/29 cruise, and they still take reservations at the Rockin' Bar D. We were able to get Palo and Brunch reservations, but not High Tea. The cast member was pretty short with us because we didn't know that there weren't any High Tea spots left and there were limited brunch spots left, and we were trying to schedule things to fit in with the shore excursions, etc. It was pretty frustrating.
IMHO, I wish they would figure out a better system for taking reservations. The way it is now, only those who get on early have a chance at High Tea and get better times for the other Palo meals.
