Thanks everyone for your great comments. I am thinking more and more that it is worth it for the convenience. We will be at the MK for 3 days: two days for the park itself and another day for the
MVMCP. The only other parks we are going to are the AK and to Epcot for 1 day each. We will be attending a few character meals that will be in the MK vicinity too.
I also was rationalizing it because the parks close early those days in December so I would rather be a 10 minute walk from the CR hotel to minimize travel and maximize park time. Its going to cost another 800-1000.00 just to do this... I think its worth extra money but not sure if its worth $800-1000.00 extra ya know?

I mean I can do the same vacation at the POFQ for half the cost of the Poly or the CR. I am very torn.
