Rumplemom,
We have been several years at various times in January and all I can say is Yes, you will see some. They come down rather staggered. Last year we where at the Poly and they where still up the last week of January, where as the parks where coming down and other resorts where down. The rule of thumb from what we have been told is that they "Start" taking down the decorations the first week of January. Hopefully you "DO" want to see them, because you are most likely gonna.
