How late are ticket booths open?

[123SA]

I don't think I've ever actually purchased a WDW ticket at a ticket booth.

I want to purchase military tickets for MNSSHP Sept 1. I don't want to do it the day of. However, on August 29th, Magic Kingdom closes at 7pm. I will be leaving MK around 7pm and heading to Poly for dinner. If I stop at TTC around 730pm, will the ticket booths still be open, and will I be able to buy tickets for MNSSHP on Friday Sept 1st (as opposed to the party that will be in progress)?

Thanks for your help

You could stop at City Hall in MK on your way out.

But, as long as MK is open for guests, the front gate Guest Relations will be open.

Likely TTC ticket booths, too, but no guarantees.
