I'm sorry but I have confliciting news with the poster just above me. We went to the 9/5 party and we got our stroller for free. Not sure if it was timing or an uninformed cm but we received a double stroller most definitely free from the normal rental spot right after we walked thru the turnstiles.
As stated before, party was awesome and had little to no wait time on all rides. merchandise was pretty cool as well, the shirt theme this year is sort of a Haunted Mansion one (which I love, so yeah for me). Now that I think of it I'm not sure if that was the official t for the event or not but I am pretty sure it was. Dark grey or black and has the entire mansion on the shirt with the fab 5 on the scene. Sorry, no picture at the moment. Pins were cute individually but I was disappointed with the frame set, it is, IMHO, quite plain and boring.
CM's were great, we ate at Liberty Tree just before the party and the characters were dressed in Halloween costumes as well as all the cm's dressed like Haunted Mansion cast members.
Some characters that stood out for us were actually Lady Tremaine and Anastasia and Drezella (sorry for the spelling). They were back behind the castle and were absolutely fabulous in the way that they interacted with the guests. Jack was awesome as always, and the parade is a must see.
Overall, another great event that will have us back again later this year.
