For pictures and more information there is link in my signature about my experiences for the past two years. However, I can give you more of an idea, the PP covered it pretty well. I love the signature events and have done the Cooking School for the past two years, and will be there on Saturday
However one doesn't need to attend the pricey events to enjoy it, you just need to have admission to DCA. If you're familiar with DCA they set up the Culinary Demo tent in Sunshine Plaza. This is where all the food demos take place and 1/2 an hour beforehand is usually plenty of time to get there, unless it is a Celebrity Chef then you'll need to get there at least three hours in advance if not when the park opens!
It's really fun if you're into food and cooking, they show you how to make something and then you get a little plate of what they made. This year they have a new section which should be a little bit more like the Epcot Festival where you can purchase small plates of food specially prepared for the Festival. They'll also have wines that will pair well with the food.
There is wine tasting on the patio next to the Wine Country Trattoria, as the PP said this year they are charging $1. I believe she also gave you a link to the schedule which was just posted a couple days ago. The beer & spirits tasting takes place down near the Mexican Restaurant at Pacific Wharf. They don't give you much but I found the information that our hosts gave us to quite fascinating.
There is also an "adults only" lounge where flights of wine are served and little bittes of food upstairs at the winery. We went there twice last year and got a cheese plate with some flights of wine and another time, I got their filet mignon sliders. They will probably have all different food this year.
We check into the VGC on Friday and will be staying until Monday. We will hopefully check out some of the available selections as soon as we get there, and I'll be posting pictures and reviews of everything I do and eat.
