Hi, all. First time posting. Here's are situation: DH, DW, DD8, DS6 at Disney (4th time) 9/14-9/18. Staying at AKV. Flying in 9/14 and out 9/18, so likely no parks those days. 9/15 is Halloween party, so tentatively planning MK that day, then Epcot 9/16 and AK 9/17. Main question is: should we do the Halloween party (and not visit the park beforehand)? Are fastpasses available during Halloween party? We want to ride some of our favorites during the Halloween party (or, perhaps, visit in the morning and come back for the party). If no FPs, could we expect to do Peter Pan, one of the Mountains, and maybe 7Drawrfs? Any advice is appreciated.
