So far, several of us -- since about 10:00 -- were directed into a "more than an hour" park reservation queue after paying for our GC hotel and tickets. Now that the site is back up and "recalculating" is gone, I am still at "more than an hour." I did notice that there is no record of my hotel reservation or tickets on the Disney site, however, although I got a confirmation of payment and a reservation number. When I put that reservation number in on my Disney account, it says there is no record of the reservation.
I'm about to give up.
