Hey,
I just tried the code and a cast member checked if there was a pin tied to our home. There was not.
She said they are getting lots of calls from people asking about this. I asked what happens to those who booked without a pin..
She said they are running a query of thier system and those folks will have the discounts removed.
Take it for what it's worth....
We're going in May, 13-22, can't complain we got our hoppers for free and waterparks too. I would never have paid for waterparks.
Goof luck to those of you who were able to book without a pin.
