Thank you for all of the feedback! Seems like CR is the resounding favorite. We stayed there last year and the convenience factor of walking was a huge +, but were curious if we should try something new. AND.... The Grand Floridian just opened up as well: Outer Building, Lagoon View with 2 QBeds and 1 Day bed. I am not familiar with the GF....pricing is the same as CR for the dates we are staying. I know we can't walk, but is it worth the switch from CR Park View to GF?
GF is gorgeous and has more amenities than any other WDW resort (more restaurants, shops, etc.). The decorations at Christmas time are out-of-this-world amazing. We stayed outer building, lagoon view two years ago (4th floor, Boca Chica) and had a slight view of the MK fireworks which was lovely. Again, it comes down to what your priorities are. If you want a gorgeous, well-themed resort with monorail access to MK (and EP by connecting at TTC), GF is great. If you want walking convenience, CR is the way to go.
In terms of travel convenience, I would rate your four resort choices in this order:
1) CR (walk to MK, monorail to TTC for EP, bus to DHS/AK)
2) Poly (monorail to MK, walk to TTC for EP, bus to DHS/AK)
3) GF (monorail to MK and TTC, bus to DHS/AK)
4) CCV (boat to MK, bus everywhere else)
If you are willing to put Minnie Vans into the transportation equation (if they are available at the MK resorts by Christmas), you would make any of these resorts more convenient.
In terms of Christmas decor and overall theming:
1) GF
2) CCV
3) Poly (normally this would be a little higher on the list, but not for Christmas decor)
4) CR
Are you planning on any future trips when you could try a new resort then? This would factor into my decision. If the answer is yes, I would probably stick with CR. If no, I would probably try something new.
