Hi Sandra! Thanks for bringing your question to us here at planDisney.
Let's get right to your question since it looks like you are planning on heading to the parks TONIGHT! At this time, all Guests ages 3 and up must have a
Disney Park Pass reservation in addition to a valid ticket in order to enter a theme park, no matter what time they will be arriving. This includes partial-day tickets offered for conventions and conferences, such as your Twilight 5 PM Ticket, which allows admission to one theme park after 5:00 pm. The only exception to the Disney Park Pass reservation requirement is for specially ticketed events, such as
Mickey's Not-So-Scary Halloween Party or
Mickey’s Very Merry Christmas Party.
I do hope you'll be able to secure the reservation you need so you can enjoy some fun in the parks during your convention. I just took a look at the
theme park reservation availability calendar and I see that as of this writing, some, but not all, theme parks have Disney Park Pass reservations available for today/tonight. If you have any additional questions, please stop by and see us again. We are always happy to help.
Anne Marie
