We were "hassled" when we used these tickets at the end of August. It was at the Magic Kingdom, the ticket agent was very agitated when we tried to redeem them. He asked where we got them, I showed him the paperwork I had, he made a phone call, (we heard him telling whoever he was talking to that 'these people aren't German, and are trying to use German passes') and finally redeemed them, but was very rude about the whole process. He said we should have never been allowed to purchase these tickets, and that he did not have to honor them, but would as a one time courtesy. Set the mood for a poor start to our trip. I want to say his name was Steve, but really can't remember, because I wanted to put the sourpuss out of mind and get on with our trip.
After we finally got "approved," we never had another problem with the tickets the rest of the trip ~ the meal voucher worked fine, and we also used them at Kennedy Space Center.
