Problem I’d have is my daughter will be 15, so I wouldn’t be able to bring her without a ticket. Don’t think she’d ever forgive me if I saw Taylor without her!
This is slightly fairer than a regular pre-sale in that it's available to anyone keen enough to sign up, rather than being limited to e.g. those with an amex card. It's a marketing ploy really to get some hype going. I think there still weekend tickets available and a few Friday VIPs, or you could try the resale sites a bit later on - Tixel and Twickets only allow cost price plus a small fee, and there are always people who find they cannot go for some reason.
