Hi! We have gone to the party the last 5 Novembers and have tried every combination possible for dinner lol! last year we went to the party at 4 and ate at Pecos Bill - Counter Service and the two years before we ate at Ohana and Grand Floridian (character meal) at 5 and then took the monorail over and got to the party around 7PM. For us, those hours that the park people are still in the park and they let party people in are crazy and chaotic and you can't use a fastpass unless you went to MK that day... so, I think through experience we have learned it is best to make an ADR at 4 in the park or around the park at a hotel on the monorail to avoid that 4-6 timeframe!
