Here is my response from e-mailing Photopass:
Greetings Leigh,
Thank you for your recent visit to DisneyPhotoPass.com.
The pre-arrival savings offer is made available through the marketing department of Disney Destinations. In order to receive this prepurchase offer, the guest must meet the following guidelines:
-Have an upcoming reservation in a Walt Disney World Hotel
-Have their email address on file in the marketing database
-Have opted in to receive email from the Walt Disney World company.
If you meet these requirements, you can expect to see this email (called "Magical Musts") about
10-45 days prior to your arrival. Note that the email contains planning information for your trip and that the Disney's PhotoPass offer is just a small section of the email.
Once you have received this email, you are within a safe time frame in which to make your prepurchase without worry that your promotional
credit(s) will expire.
*Please note that this link is only available for one pre-Purchase offer and must be purchased prior to your arrival date as this is directly linked to your reservation. This link is non-transferable. This offer will expire at 11:59 PM the day prior to your arrival date.
If you do not receive this offer, it could be because your email address is not on file and/or permission was not granted to send marketing messages to you. Also, if you booked through a
travel agent, we may not have your email address in our database.
If you are a Disney Vacation Club member please contact member services at 800-******** for further assistance.
The pre-arrival savings offer is meant for guests who purchase before their trip.
If you have lost your email or offer, we regret that we are not able to replace or extend it as this offer is not sent out by DisneyPhotoPass.com.
Sincerely,
Deborah
Disney Photo Imaging Guest Support Team
