UPDATE: In less than 3 hours, it appears that all available dates in the month of September have been booked by Passholders.
Passholder Play Time is now open for reservations on every Tuesday through Saturday in September. Passholders must receive an email invitation in order to sign up. Apparently not all passholders are receiving the email at the same time today, in what we assume is an effort to spread out the signups so as to not overload the servers. But we have the secret link for you! Just GO HERE to log in to your Disney passholder account. Once you log in, it should automatically forward you to the signup page, but if not, click THIS LINK after you have signed in.
The benefit is only available to Gold, Platinum, Platinum Plus, and Premier Passholders. Two time slots are available, 7:00-8:00 AM or 8:00-9:00 AM, on each day. It is not clear whether those that are in the land for the early time slot will be forced to leave the park at 8:00 AM, but we would assume wristbands will be given out and that guests in the early contingent will not be permitted to enter ride queues after 8:00 AM. Whether they will be escorted out of the park or allowed to remain in the park until normal opening time is unknown at this point. If the early guests are allowed to remain in the park, they would theoretically be first in line for another ride once the official opening time of 9:00 AM comes around.The server is very busy right now and giving many guests problems booking the free offer.
