Yes! There is a thread, but I am technically challenged and don't know how to post the link. Is Maggie doing it? I walked with her last year and had so much fun chatting about WDW with her.
DH Jim and I are doing it, as well as Liz and Patrick, and Susie (escape) and her DH are coming from out of state! The tentative plan is to meet at the expo and then perhaps walk to the same pizza place as last year (unless something closer catches our eye).
I think a few other people are registered too, but my memory ain't what it used to be!
