I've never heard of such a ticket, but I've had an AP most of the times I've gone.
I just got an email back from them, this year they will not be offering it.. here is what they sent:
"Thank you for contacting Universal Orlando Resort™ Guest Services.
We are committed to providing the most frightening entertainment experience possible during our annual Halloween Horror Nights™ event. I do regret to inform you that we do not have a ticket allowing admission to the park at 2:00PM.

On Halloween Horror Nights™ event dates, Universal Studios Florida™ will close daytime operation at 5:00 PM so that we can prepare for Halloween Horror Nights™ to begin at 6:30 PM. If you are inside the park before 5:00 PM and have a Halloween Horror Nights™ Add-on Ticket for that same evening, you are welcome to remain in the park at a designated waiting area for the event to begin. Our Team Members will be happy to direct you to the location of the waiting area on the day of your visit. You must present your Halloween Horror Nights™ Add-on Ticket to be admitted into the waiting area. If you decide to exit the park for any reason before accessing the holding area, you will be able to re-enter the park for Halloween Horror Nights™ at 6:30 PM with your valid Halloween Horror Nights™ admission ticket.
