July 7th for November 4th??

[JJ2017]

Ok - I will be on the road, and have to book park reservations so I want to be sure I get this right.

We are looking to visit the parks on Thursday, November 4th. 120 days before is Wednesday, July 7th, correct? And it seems as if the date opens up right around 9:30 am EST.....

I have two comp tickets and I have to buy two more. I don't know right now if my comp tickets will work for this exact day, but I want to attempt it. Should I buy the extra 2 tickets now, or just wait for the day of booking process to make sure the date is open?

Thanks!
