I have yet to go in December (but will be in Epcot on 12/22!!), but I don't think that is likely. Rope drop SDMT lines are still fairly long. I would either FP PP, too, or consider doing SDMT for a 2nd ride near closing and rope drop PP. Have you plugged this scenario into a touring plan? I find the a.m. Predictions have always been very true to real time.
