When we ate at Liberty Tree Tavern last December they were there as well. Not sure if they still are, but that might be one other place you can find them!
They were at Cape May Cafe at the Beach Club for breakfast when we were there...but we did not like this place very much. I also hear they are at Garden Grill!
I heard they were being removed from Garden Grill too? Surely they must be somewhere, they're my DS6 favourites, he sleeps with Chip'n'Dale soft toys every night! Although our option to guarantee seeing them was the campfire movie night at Wlderness Lodge Campground, that sounds like a fun nught - and it's free!!
