I was just there from the 28th through the 1st... I rode a bunch of rides over and over again, met Merida at MK, did a ton of pin trading, finally saw Fantasmic, and had fun at
MNSSHP.

The Halloween parade was great, and I'm not a big parade fan.
My favorite part of the trip was my dinner at California Grill. I had a seat right by the window facing the castle, and the HalloWishes fireworks happened as I was eating dessert. Absolutely fantastic. I also ate at Mama Melrose and Biergarten, and had the filet and cheese soup at Canada F&W. All of the food was great, but California Grill was just amazing.
It was pretty cold in mornings and evenings, but I liked the weather overall. I did have to buy a blanket to use while waiting for and viewing Fantasmic, though! I brought hoodies and jeans with me, but I didn't bring a coat or gloves or anything like that.
Thankfully, my hometown was pretty untouched by Sandy while I was gone. I had to leave for my trip a day earlier than planned, but neither Disney or JetBlue charged me a fee to change my reservations. So, I got an impromptu extra day of vacation.
