I just got an email...
"We just want to inform you that your DISApalooza Wizarding World of Harry Potter Event Credentials have been mailed to you.
These are being sent via USPS Flat Rate Priority Mail and you should receive them in 7 - 10 business days.
Credentials will be required to attend the party. If you lose, alter or do not have your credentials you will not be permitted entrance into the event. Absolutely no exceptions will be made. Your party credentials are NON-TRANSFERABLE.
No park admission media is required to attend this event - just your party credentials.
Furher instructions will be included with your credentials.
We look forward to seeing you there!!!!"
Frankly, with Priority Mail, I would expect a much shorter transit time, so no worries mates!
