HI,
one step of advice is to also make sure you have the park hopping option on your tickets, especially when you are staying for a wonderful 10 days. You will then be able to go to multiple parks in a day, like Mk in the morning and maybe epcot in the afternoon after some rest if needed. You will be so glad you added that.
I know I called for the "code" back in Jan for December and I think I remember them saying that the code was good starting Dec 7th-14th. We were going to go Dec 6-13th originally and had to change our travel dates.
I just called Disney reservations and asked if there were any promotional codes associated with my name and sure enough it was there. THere is a post above that gives better advice on what to say, you may want to try that. I also know that when I called
AAA they gaveme a very good price too, so if I did not get the 40% code, I would have booked thru them.
Another tip is to try to do one of the frig swaps especially since you have along stay. Most are free, and the last time we were there, staying at ASMu, we did one and we were glad we did. Great for left overs, chilling water. keeping milk and yogurt in the room for snacks etc... Look here on the boards and find out all about it.
Pick a night to go to
MVMCP! well worth the money! Even with small kids.
We also love the candlelight processional at Epcot and Osbourne lights at DHS. All awesome Christmas things to do and see.
So much information...........keep asking questions!!!! GOOD LUCK!!!
