TBH, this makes me happy. When it rained during the marathon and we didn't spend the time in WS that we might have otherwise, we felt really rushed to get to Epcot on Monday (plans for Sunday were set) after an MK morning/afternoon to make sure we got in what we wanted on the last night of F+W.
This year we're going for the marathon again, so it's nice to know that if it rains again we will not have to worry about the festival ending before our trip ends. Also, hopefully, maybe crowds won't be quite as high with it not being the very last weekend of the festival as well as Veteran's Day/marathon weekend. (not that I expect them to be low, I don't, but maybe just a little less)
