Candlelight doesn't usually appear on the calendar, as it is generally considered a private event available to all in the park (yes, that sounds weird...) It will be the 3rd and 4th. First showing is at 530, second is at 8pm.
It used to be there was dining packages, but they usually sold out in under 5 mins. It is a great event, but seating is very limited. There is a lot of standing room, but it is usually full quickly. My suggestion is to try for the second show. They line up on Main St when first show starts. There are a few here who can probably help with when and where the lines are.
Here is a clip from it my daughter did a few years ago with Edward James Olmos. (We love Drew's voice, he is one of the Dapper Dans.)
It is my favorite way to start Christmas month.
