This will be our third December Disney trip -- I'm SOOOOOOOO excited.
Some of the highlights for us have been:
*Definitely the Osborne lights at DHS ... the first time we went, when it started snowing & we didn't expect it ... total magic. Seriously.
*Characters are often in "winter" outfits if not specifically Christmas. Pooh & friends at AK had on scarves & hats, Mickey & Minnie at Camp MM were in christmas attire, etc.
*last year we saw both the Beach Club gingerbread carousel (neat, but I wouldn't travel there for it unless you were there for another reason; the kids really enjoyed finding the hidden mickeys though) and the GF gingerbread house (beautiful, the whole place is great & we got some AWESOME pictures in the lobby by the tree & the house before our 1900 PF dinner)
*Santa was at MK the first year we were there, down one of the side streets off Main Street USA. We didn't go back there though, there was a big line!!
*trees everywhere, love the AK parade. Also really want to do the CP this time around. We ended up having to leave a little early last time because the kids got cranky. We saw John O'Hurley do it (J.Peterman from Seinfeld) & he was great. The music was gorgeous.
*we don't do
MVMCP. I would love to, someday, but the kids just can't stay up long enough to make it worthwhile (and they do NOT nap, so napping mid-day is just not an option).
Everything is just gorgeous though, crowds aren't bad at all, and the weather has been nice generally. The first year we went it was pretty hot (for December) like 80-85. Last year it was cooler, we ended up wearing sweatshirts a lot of the time, plus we got caught in a HUGE downpour our second day there (just after getting DD dolled up at BBB!

) which was rough (just picture us sprinting to Akershus while it was raining sideways, we were already 30 min late for our reservation, had DD in the stroller with only her face sticking out of a poncho, the baby in a carrier & a poncho on me, DH & DS running with a useless umbrella ... such a comedy of errors)
I can't wait to go back!!!!!
