Well you are already signed up for two good ones, but here are some other suggestions.
1. Flag Ceromony/Tree Lighting at MK, This takes place everyday at 5pm in Town Sq. The flag ceromony is so moving and they usually have a vet or current servicemen assist them. Immediately following this is a little show on the the Train station upperdeck you can view it from town sq and ultimatley leads to the lighting of the MK tree.
2. GFLobby, plan a late afternoon or evening. You might want to go to tea. The cms come out into the lobby about 4pm and sing carols, followed by the band and Pianist. Dont miss the huge gingerbread house where you can nibble on some wonderful morsels. You might even catch them roasting chestnuts.
3. WL, the lobby is truly a beautiful sight. We sit in the rocking chairs in front of the fire and just people watch or eat at WC.
4. EC Take time to enjoy the various intl storytellers in each of the countries they are wonderful.
5. Yultide tour. If you have time this is a wonderful inside view of just how they decorate wdw. You visit three parks, a resort and the xmas warehouse. (407)wdw-tour
6. Sleigh Ride/Hayride. WL has the sleigh rides and FW has carriage & hayrides nightly. You will need resv for the sleigh rides.
Have a magical time!!!
