This was our "CS Vacation, meaning we mostly ate at counter service places. We ate hotdogs at least 4-5 (maybe more) times on this trip and I was worried about the wheat buns too, after reading about it here.
To my great relief not once were we given a wheat bun........NONE. LOL
I'm trying to remember where we ate but we hit SO many CS places it's difficult to recall. We had dogs at two locations at the MK, Epcot by the entrance to the WS there's a new building and they have hot dogs there, the hot dog stand on the Boardwalk and a hot dog place at Downtown Disney. We did not eat at Casey's as the line was always too long to eat there.
Our trip dates were Jan 21 - Feb 1
