Uh...let me try to explain this in english...when the Fd went available online I logged in to shop for our September trip. My first try, only standard rooms were available at Pop. If I wanted a preffered room I had to check inn on the Saturday instead of the Sunday, wich made our trip an 8 nights stay. Later that nigth I went back and all room categories were available, for a check inn on Sunday. I waited in the morning to book 'cause I wanted to make sure with DH, again only standard rooms available
I waited like 10 minutes, went back, again every categories were on again...
Bottom line a Cast member once told me they see the same availability that we see online. Don't give up and try again later.
