I just went to this - this past Wednesday. For refreshments they give lemonade and water...and snacks are bags of Cracker Jacks or Popcorn.
They have everyone fill out a card and drop it in a box and they pull 4 names and those 4 people go up and play a game that tests your knowledge of DVC. If one of the 4 don't know an answer and an audience member gets it right, they get a small prize like a DVC keychain. I left after a few questions because my 3 year old was miserable. I did see some people come out afterward (from our balcony) with DVC baseball caps but I am not sure if everyone got one or if they were winners. I believe there were 3 small baskets they gave away as prizes too, I saw them displayed when we entered the dance hall.
But that was the general idea. Hope this helps!
Are welcome home wednesdays something they are doing for a limited time period, or something that will still be going on when we are there again next June?
