Well, Epcot was the one park I never worked at. From what I could tell it seems cool. I believe each booth has just 2 people and usually 1 greeter. Everyone I knew at Epcot seemed to enjoy it a lot. Definately a different pace from TTC. And I know you guys have an extra ticket that we didn't normally sell, if they still have it anyway. It's an after 5 or 6 pass for FL residents.
I stayed at Chatham when I was down there and loved it, except my bedroom was right near the entrance.
I can truthfully say that there may be days when you want to rip your hair out, but it's fun. The time around holidays are the worst. It's mainly stressful because Disney sets a total that they would like you to meet, and people will try to pull things at the counter(i.e. trying to get a FL Res Discount, Quick Change Artists, try to get you to let them in for a cheaper price). Then there are times when it's really busy and you just can't take the time you need to with a guest. Those are rare occasions though.
Oh and Disney also has a phone line to help you assist non english speaking guests. TTC is generally the busiest of the 4 VP areas, as they get a ton of single day visitors. The other three tend to get the more weeklong guests.
