"Which park is Coronado close to as far as driving? WDW,Epcot,MGM,AK."
Coronado Springs is down the road towards Animal Kingdom, but might be just a bit closer to MGM, since Animal Kingdom is so far out.
"Is there anyway you could get there from the park without having to drive? Do you have to take a bus or is there some other way?"
All you have to do is catch one of the buses at one of the parks or Downtown Disney to Coronado Springs Resort and get off at the main building.
"Did you have to pay for parking to eat at Coronado?"
No charge for parking. Just tell the person at the security gate that you are going to have lunch or dinner at the Pepper Market.
"And lastly what was the procedure you have to do in order to use the Quick & casual vouchers?"
This I don't know the answer to, as we are going to be using them for the first time this December. My guess is that you just tell the server that you are using these and they will know how they work.
"Where did you eat at Coronado?"
The Quick and Casual Vouchers are good at the Pepper Market, which is Coronado Springs version of a food court, although you have a waiter and are seated by a host/hostess.
Have a wonderful trip!
