OK... that junk Computer System is starting to get REALLY bad...
This had nothing to do with the "Website". The basic back end Data Base Systems are just FAILING. Think ancient mainframes....
Please, CAPTURE all reservations ("print to PDF") the moment you get them. KEEP that data on your cellphone. The WDW computer SYSTEM (cute front end Web Site + multiple ancient Data Bases + ZERO change control) should be considered "suspect" at all times: IE, it can LOOSE DATA.
PLEASE - capture that data, and be ready to present it?
And PLEASE... consider using our board's CENTRAL THREAD for WDW IT issues?

All personal opinion - I'm not necessarily right, no one else is necessarily wrong.
