Could you fit both in? Don't give up your ADR just yet. I took my kids to CRT when they were 6 and 3 and it was magical because they got to meet so many princesses! The food was just so-so, but we didn't go for the food. That same trip, we went to dinner at 1900 PF and loved it. Again, the buffet was not that good but the kids just loved seeing Cinderella and her handsome prince. The stepmother and step sisters are hilarious and provided some of the best character pics of our whole trip.
We are returning in the fall and only have four days but now have three kids and want our daughter to have the same fun experiences so both of those meals are on our agenda.
