At this point, no one has done this package so it's hard to say if it's going to be worth it or not, both in terms of parade viewing and fireworks viewing. You'll have to wait until the reviews start coming in after the first party to really know. The PtN viewing area is down in Town Square (at least from last reports), but it's not known if they're go use that same area or not for the Frightfully Fun Parade. Last year, PtN followed the same path during the MHP as it did on normal nights, so it went by Town Square, but in previous years, Cavalcade did not. Also, it depends on when the shows start. PtN started at 8:50 pm and fireworks were at 9:30 pm, so there was almost no time to move anywhere, but the Cavalcade started at 8:30 pm, so there was time to move to a different fireworks location.
