Did she say you could on the 13th? I keep reading online only purchases on the 13th. So I wonder if we are attempting to trade in unused tickets, and we have to call, I'm wondering if we have to wait until the 20th? Of course the guy I spoke with yesterday literally said they hadn't decided yet and we would be getting an email. I just don't want to bite off the 10 day hopper tickets and then be told I have to wait to exchange until the 20th. With my luck they will be sold out by then.
