I was lucky and I was able to book the tour for our vacation in May. I called right when they opened at 180 days. The cast member was excited that she was able to actually book the tour - it was the first time she was able to do so. It turns out it is the same day as the AK Moonlight Magic, so it is going to be a long day for us. I'm planning on doing the tour, Epcot in the morning and then taking a break at our resort (Poly) in the afternoon, before going to AK for the party that night.
