Something like that was allowed 2 years ago when they overbooked the free dining plan. There has been no talk of it since, so I doubt it...you can always ask, but I would not plan on it.
They did something last year for free dinning that if you ate at a counter service and used a table service in place of a counter service they gave you a voucher for 2 additional snack credits. As far as changing a table service for 2 counter services i am not sure about that one-- but anything is possible
ya... it was 2 years ago when my cousin went and this is what they did for a few of the days. I have never used DDP bc we have AP's. I feel like I know nothing!
