The language still states this [Limit ONE (1) ticket per reservation, per person, per event date.], so I'm still trying to figure out if you can register two people. Because it sounds like you either need to register separately or register one after the other, both seem to be in danger of one person getting in and other other getting shut out.
The Parks Blog says this:
Event Ticket Tip: When purchasing the event ticket, you will be allowed to purchase one (1) ticket per person, per event date, per transaction. You might wonder why, and it is due to the merchandise offerings that will be released in conjunction with the event which requires each ticketed event guest to have a unique registration ID.
I totally get that, but I'm still confused as to the actual logistics involved. Ha!
