It shouldn't have anything available for booking this weekend though? My letter from Disney says:
I am sorry to inform you that the Caring for Giants program at Disney’s Animal Kingdom is currently closed through Monday, September 25th. Although Disney’s Animal Kingdom Theme Park will be open during this time, the backstage location associated with this program remains closed due to the recent storms in our area. We currently have no confirmed date when we re-open.
You currently have a reservation for 5 @ 10:30 am Sunday, 9/24. If you would like to re-schedule for a date after 9/25, please reply with your future date and time preferences. Programs run 7 days a week, with 10 sessions a day, starting between 9:30am and 4:00pm.
My previous letter back in June from Disney:
Thank you for your interest in Disney Youth Programs at the Walt Disney World Resort and for registering for our Disney YES Individual Enrollment programs. I regret to inform you that these programs have been cancelled for the remainder of the year due to restricted availability in our parks while we undergo construction. We apologize for this inconvenience and want you to have as much notice as possible.
The program cancellation will not impact your theme park ticket usage at our theme parks. Please continue to enjoy the parks with these specially priced tickets that you purchased.
We would like to recommend a family-friendly tour at Disney’s Animal Kingdom called Caring for Giants. Our team can assist YES Individual Enrollment registrants with signing up for this unique experience. Our records indicate you had (4) guests registered to attend programming.
If you have additional family members who have admission tickets, but were not registered for a YES IE Program they may also book this tour for $30.00 by calling 407-WDW-TOUR.
