NO! The beauty of the Disney After Hours events is that you can buy an after hours event ticket to get into the park without having to also purchase (or use one of your days) a park ticket. It is your park ticket and the key to your up to six hours of Disney parks fun! And to be honest - I think we were able to do way more in the few hours of the event than we could've done with lines and crowds during a regular busy day in the park. We were definitely able to do more of the popular rides at least. If you need regular park tickets, you can get them for a discounted rate from Get Away Today here!
