We are heading to DW this Friday for our first trip. We don't get in until around 9pm on Friday and are hoping to head to the parks early the next morning. We haven't ordered our tickets yet, so I know we can't get them mailed to us but I was wondering if we could order them and then pick them up at MK, where we plan to go Saturday morning? If so, what time do the ticket offices open at the park? Thank you.
