We often do wine on the balcony when staying at YC. While I agree bringing your own works -- I just wanted to mention for those who may not know, or if bringing your own is a hassle, there are some adequate bottles at the YC gift shop at an okay price (really), more choices at Boardwalk gift shop. Same goes for Italy and France in Epcot. (I think at Germany too, but I don't like German wine, so not as familiar.) Some of the Epcot choices are not ridiculously overpriced.
Yet another reason YC/BC rocks: proximity to Epcot as a wine store.
During F&W, the festival center has wine and spirits, some of which are not overpriced.
