For our Platinum Pass packages, we purchase blocks of rooms in our host hotels. The price of the rooms are then passed on to you via the purchase of the pass. The hotels literally have no record of your transaction at that time.
As the expo approaches (and we have sold out of Platinum pass packages) we then turn in our lists to the hotels and rooms are assigned. Even then, the rooms are not held under their normal reservation system. Instead they are handled by people assigned specifically to our blocks. If you think you need to check on the room reservation from your Platinum Pass package, please contact us directly at firstname.lastname@example.org and we will help you.
