No, there have not been any since August I believe. I don't think there were any in September. As for October there was the Halloween Parties (so no e-nights), November didn't have any scheduled, December has the Christmas parties (so none for that month either and so far there are not any listed for January.
I would LOVE an E-ride night, but I guess there's no way to predict. We had one on our last trip, and it was announced pretty close to the date, so I'll keep hoping until we get there.
I don't think they would have them around the holiday time because MK will be open late anyway. It was a LOT of fun, and if they ever offer it again when we are there, we will go!
