I attended 8/31 as well.
The good:
We liked the food offerings --especially the cheese fondue. The popcorn was a big hit too. The adult drink selection was nice as well. We preferred the selection at this party over the selection at the Star Wars dessert party.
We especially liked just sitting as a family and being able to talk for a bit.
We liked walking out of the park when it was fairly empty. The photopass photographers were still out, so we got some nice photos
The bad:
I feel like I should have received a discount for my obscured view. We were at table 25. IT was to the left of the bar along the fence (as you face the bar). I had read at some point that tables were assigned in the order it was reserved. I don't know. I was on-line booking it literally the moment it opened, so I'm not sure this is true. It is possible that Disney attempted to "accommodate" us because we had a wheelchair -- this happened at the Star Wars dessert party. (I didn't ask for the accommodation, I don't know how they knew we had a wheelchair in our party, and I didn't want it. Yet I was stuck with it. I had to track down a manager in order to view the fireworks with my son, husband and daughter -- the handicapped viewing had a total of 6 groups in it. It was about 1/3 full and the attendant said that me and my 11 year old couldn't go in. We were a party of five, all walking together and she dropped her arm down in front of me and said no. It was too crowded. We were the only people stopped. I'm sure of this because we were the last of the group. If they hadn't made us go to that spot, we would have just gone to the regular spot and watched it altogether, but of course by this time it was full. I found a manager who let us sit with the rest of my family.) Anyway, when we sat down at Epcot, I immediately thought that the view wouldn't work, but I convinced myself not to go complain. I was still angry about the Star Wars Dessert party and figured I was just being sensitive. I hadn't seen the show from this angle before and I stupidly assumed that of course we wouldn't spend $$$$ to be seated in an area where you cannot see the parts of the show that take place on the water. Our table was behind a very large bush and some strange pole. We were the only group that had to get up and find an area to see the fire part and the globe, which wasn't easy since I didn't want to step in front of another table and obscure their view. Once the fireworks started we sat down again, but I had to get up again to take a photo that wasn't of the pole. Honestly, this table was not at all acceptable. I loved the party, but unless they can guarantee that I wouldn't have to sit there, I wouldn't do it again. If you find yourself behind that bush and pole, ask to be moved immediately.
(Apparently there is a water fountain during the show too, totally didn't see that at all.)
