I'll be listing mine as Disneyworld Christmas Village Magic Kingdom but I've seen them listed under Disneyworld Christmas Light Up Village and I think the Dept 56 ones are something different.
I'm not listing mine as "light up" because I have no idea if the lights even work... I never even realized there was a spot for an AC adaptor until I was getting ready to unload them
Mine never came with adaptors and they've just been on a shelf for a few years. How I did not notice that they had a spot for an adaptor... who knows?
They usually sell for around $40-$90 on Ebay. Casey's Corner seems to be the most popular and hard to get one. I've seen that one go for $120 before. I'll be listing the castle & train station in a few weeks for less than retail but again, they aren't new and I honestly do not know if the lights work.
They are really pretty. I just have no room for them.
One thing I can say, if you get one off Ebay, make sure whoever you get it from packs it super good and guarantees their shipping, esp. if you get the castle. There is a teeny tiny Tinkerbell on top of the castle that is barely attached and if it's not packaged by someone who knows their stuff, Tink will snap off.
That's one of the reasons I haven't listed them yet, because I know it will be an ordeal to ship.
