Can anyone explain to me how this works? I just read about the candlelight procession and it sounds like something I'd really enjoy. We are going in Dec. and already have reservations at the San Angel Inn one night, which is one of the restaurants offering the package. However, we are using free dining. Is there an additional charge to secure a seat for the processional? If so, what is it? (I couldn't find it on the DIS site.) Can we just add the package onto our existing reservation? Thanks!
