Yes. If they didn't, that would leave AP as the only table service restaurant on property, and I don't think AP could handle the load. While character meals are perhaps a way to get people into seats, those same people tend to linger longer to ensure they meet the characters.
I've been contacted twice by Disney after sending emails to (a) ask what is going on, and (b) how achingly disappointed I--and many others--would be if AP goes to characters for each meal, realizing as I do that the rumor is unconfirmed. Both times, they have spouted the same company line: "We know people are passionate about things such as AP, and we thank you for that passion. We have no actual news at this time, and in fact, I have heard nothing. Further, you shouldn't listen to all the rumors from various sites and sources as only the Disney sites are official, and that's where you will hear when anything is released." Of course, I pointed out that the very reason people turn to other sites and sources is because Disney usually says nothing in advance of a change, and such is the case with AP. We KNOW something is going on because of the lack of ADRs there come late October, and since Disney deigns to inform us of why or when or what to expect, and since Disney has forced us to begin planning many months in advance--especially ADRs--and because more information is better than no information, of course we are going to turn elsewhere. Given Disney's poor lack of foresight with the recent construction and refurbishment at WL, I have no faith they will make things better with whatever change is coming to AP. I do sincerely hope that I am wrong and will gladly eat crow if I am.
