We were trying the vouchers for the first time as we had read quite a bit of good posts in various places on the board. I purchased ours through the disauctions for about $12 each to avoid any of the membership issues. Anyway, we went to Beaches and Cream one afternoon at about 3:30 for our first try. This was also an opportunity to park at the Beach Club resort and then walk into Epcot via the International Gateway entrance and avoid the mobs leaving the park after Illuminations through the main entrance. Beaches is a sit-down restaurant with limited seating so you will likely have to put your name on a waiting list and get the beeper thing. It wasn't a long wait so we wandered around the resort. They have a somewhat limited selection of main courses (Hamburgers, Chicken sandwiches...lunch type stuff) They have a Prime Rib sandwich which has received good reviews here, but they were out of it when we went. Another post elsewhere mentioned that they may discontinue this as they are losing money. We got Hamburgers and Chicken, onion rings, soft drinks and HUGE sundaes for dessert. It was definitely worth it. The waiter was very helpful in telling us what we could get. We only used 3 vouchers for 6 people (2 adult, 4 kids)
Later, we visited the Pepper Market at the Coronado Springs Resort. PM was better for food with a wide selection and nicer, bigger eating area. Both were a great value with the vouchers. At Beaches, we got some extra drinks and had a separate bill for those. At Pepper Market, we just got the exact items on the vouchers and walked out without paying a cent. Very friendly in both places. Sorry I can't give you more experiences. All the places you can use the vouchers are listed on them, but many of the places, especially in the parks, are pretty lame in the selection to really get your money's worth. Hope that helped!
