That's a really good question Diane!
I'm pretty sure it's on the park maps. It used to be, but I haven't really read "The Fine Print" in quite some time.
Does anyone know the answer to this for sure?
That said, I'd like to see WDW do what many other theme parks have done--offer a picnic grove outside the gate. People can bring their lunch in a cooler and leave it in their car. Then they can retrieve it at lunch time, eat in teh picnic pavillion, and return to the park. It seems that the TTC is large enough to put a picnic area in one corner of it. Maybe I just figured out a use for the Speedway
Why outside the gate? Because it would alleviate bringing a large cooler into the park, with no place to store it and one more thing to have to be searched.
For those not driving because they are staying on property, they could easily return to their rooms to eat, every resort has either picnic tables or poolside tables to eat at.
Of course for those who want to pack something small not requiring a cooler, paper plates, etc., the carry-in option still exists--at least for now.
