Our next trip (April 2012) is currently planned to be split between 5 nights at the Polynesian, then 5 nights at the Beach Club. In October, when it's time to book my ADRs, can I still book 180 + 10 on the day that I first hit the 180 day mark? Or can I only book the first 5 when I get to the 180 day mark for my first day at the Poly, then the next 5 when I hit the 180 day mark for the first day at the Beach Club?
