We did this in January '02. We had booked 2 nights at AKL and then 4 nights at CR. CR never really appealed to us, but we needed 2 rooms at each resort, and CR was $20 cheaper per room per night than the Poly (where I really wanted to stay) and we really wanted to stay on the monorail.
After our 2 wonderful nights at the Poly and a long day at MK, we checked into CR. The staff we encountered was not friendly or helpful, and we just hated the rooms - we found them so ugly and just not our style at all. So...DH kindly called the Poly and we were able to get 2 gv rooms there and went right over. We just loved our stay at the Poly - it was so worth the extra couple hundred dollars.
Oh -- we had our luggage transferred from AKL to CR that morning, so then CR just transferred it over to the Poly that evening.--
