I’m not sure that I know what a “Character Stampede “ at WL was, and we’ve been regulars there since 1998. My guess is that some Disney characters were dressed as cowboys/cowgirls and visited the Lodge at certain times? We haven’t seen that many characters over the years at WL so this is a puzzle. Frankly, it sounds like something that would fit Ft Wilderness more.
Being at WL in December will be awesome. It is by far the best Christmas decorated location at WDW since the theming lends itself to the season. Enjoy!
