We love the Polynesian and GF but have yet to stay at the CR. But we've been staying at the Polynesian since 1983 so it would be very hard to turn our back on those memories.
So we don't.

Our typical trip is 3, 4 or occasionally 5 nights at the Polynesian followed by 4 or 5 nights at BCV.
Best of both worlds for us. We love the MK resort area. The views of the MK sparkling in the distance surrounded by trees is so much more magical to us than the BW/Y&BC area as pretty as that is. We also love the monorail and the convenience of the TTC to get to Epcot. We love the restaurants in those resorts and going to dinner via monorail.
And then we move to BCV and have more room, the washer/dryer and full fridge. We usually get to see Illuminations from our room.
We don't miss housekeeping at all.
Thanks for responding to this post. I do feel so much better.
