However the PH vouchers say that it may not be used in conjunction with any other offer, so the question has been asked if it can be used in conjunction with the dining plan. One poster did say the only person eligible in their party to use it was their two year old nephew, so it doesn't look like it. I have one left from our trip last May and will be getting another one for our Sept trip, but won't use them if we can't use the free dining plan with them.
