Illuminations on October 31st

[sunergosghb]

We want to see Illuminations on Oct. 31st, but due to dinner reservations, will not be able to get there as early as we'd like. Do you think the Illuminations crowd (and Epcot in general) will be a little lighter that night due to MNSSHP? I don't want to drag our kids back there for Illuminations if we're not going to enjoy it due to poor seating or overcrowding.

Leaving in 4 days for our first trip to WDW!
