I am glad you started this thread Doot Fan Mommy because I was about to start one. I have been to Disney on Christmas before, and in December before, but it has never actually been Hanukkah during those previous trips. I have started a facebook group to discuss the topic as well. I figure cover all bases. Here is the link to the facebook group if anyone wants to join.
https://www.facebook.com/groups/1069601849781507/ It is called WDW Hanukkah 2016.
I know that Boardwalk Resort has a menorah on the fireplace, and Shades of Green has a huge gorgeous menorah on the guest services counter, but I have never seen a lighting ceremony as we never were there on the actual day.
What are you plans to bring a menorah that is electric or battery powered? I am planning to bring my electric menorah. Right now I'm researching where to get latkes. I can bring sufganiot, but its really hard to bring latkes because they'll get mushy.
