We are scheduled to do the princess breakfast for my daughter's and my birthday and November, and to be honest, I'm a bit worried about it. For the price you'd expect something spectacular like meeting 7 princesses. To only meet 4 or 5 would be pretty lame. Plus, I've heard that the later in the day you go, the worse the interaction is because the princesses get tired. But it just doesn't work for us to get up early and do a huge breakfast ahead of a park day!
The single most disappointing experience I've had at a Disney park is Cinderella's Royal Castle at WDW, and I really don't want to repeat that at 1.5 times the price. I'm really, really hoping Princess Breakfast Adventures will be a good experience.
