We ate there for breakfast last week, and it was AWFUL. Never again. Here is our story (op I hope this is something you can use to pass on)
We had a res at 10:05. We had never done a meal at another resort, so left plenty of time to travel. We arrived at poly about 9, walked around and checked in at about 945. As I was waiting in line to check in, this was the scene. There is a party of 2 women and 2 kids in front of us. She asks for a table, CM tells her they are not taking walk ups, and she suddenly has a reservation, then carries on about how angry she is going to be if "that guy" (i assumed a concierge) didn't make the ADR he promised her

So she carries on til they tell her to have a seat while someone comes out to talk to her. I check in, get a pager, sit. 1005 comes and goes. We wait. This woman who claims to have a res, and her party of the same size, get seated about 1020 while we are waiting. I mention it to DH who goes up to the podium to ask. No one will really aknowledge him. We will call you when we are ready they say. He moves on to the next CM and so on. 3 of them blow us off. So he walkes over to where they have the slips lined up on the podium for seating. We are third in line, behind a 1015 and 1030 reservation

He asked about this, and again no one will really aknowledge him other than to shrug. GRRRR. We finally get seated at 1030. We again expressed our concerns to the CM who came out to seat us, and he ignored our questions and continued on with his rehearsed speach. Infuriating. And there was an entire seating section completly empty! And dozens of empty tables besides.
So, we are seated a full half hour after or res time. This may not seem like a lot, but when you have a 2 year old, and a 5 year old, and checked in the required 15 min early this is a LOT of time. The server is nice. The man who brought our food was a little scary. Very nasty look on his face as he plopped the food into the middle, and one mickey waffle on each plate without a word and a scowel for the kids. When we sat the server says one hour to one hour 15 min tops to see all the charaters. Great! DS really really wanted Mickey's autograph! So we wait, very patiently. An hour goes buy, we ate a ton (the food was yummy). And Stitch came. An hour and ten minutes and Mickey, Pluto and Lilo finally round the corner. As soon as we can see them, they leave for a 10 minute break! Really, I know they need a break, but we have now been sitting an hour and 15 minutes waiting for them, tack on the 45 minutes we waited to be seated, and my kids are at their limit. Not to mention there are still a dozen tables between us and where they stopped. So we left without seing the charachters, very dissapointed.
