Same here! Arriving Friday. Coming from the Vegas area, we will actually be cooler than Anaheim! Frustrating! We go this weekend every year...t shirts during the day, and we pack light hoodies or wind breakers for evening. This year the kids costumes would totally be messed up by jackets, so we are packing long sleeve t-shirts for them to throw on underneath if it gets chilly. I think it is supposed to be in the 60s in the evening. We find that a little chilly. Definitely quite a drop from the hot afternoon temps!
