Well our TA tried to book us into the Miracosta on the 1st day of the 6mth booking widow, and everything was gone (except the suites in the 750K+ range for 3nts), so we fell back to plan B. We now have a Cinderella Room in the Tokyo Disneyland Hotel.
The CM said to keep watching the website as lots of people book, but then cancel (as no deposit is required as is here in WDW & DL).
