There was some sort of food reception that people somehow signed up for at the cranberry thing.. they go to walk around in it, eat food, even sit in the cranberries, but I don't know the details or even if this is what you are referring to..
When we have been there during F & W, nobody was allowed in it, which was a shame. I'd love to get in there... I'd even pay an extra fee... ...tehe, maybe they can add it to Fastpass +, a worthy Epcot fastpass.
