We had breakfast at the plaza at 10:40 and had somewhat of a similar experience. When we sat down they told us to fill as many plates as we would need because they were getting ready to clear breakfast. We missed out on several of the offerings because we weren't fast enough. Then we had a mad rush of characters. We saw Minnie, hook, Peter Pan, pooh, tigger, and eeyore all within 10 minutes. While my kids were thrilled during that 10 minutes the characters immediately went off set. We were more fortunate than you in that we got to see all the characters, but we literally sat down, were told to fill plates, and then immediately bombarded by characters. Lucky my husband filled a couple plates while the kids were playing with pooh because as soon as the characters left the buffet was half empty. If they're going to clear the restaurant of food and characters at a certain time, I think the last reservation needs to be 30 or more minutes prior to that time.
