Question for anyone whos been before. We are planning to be in MK the morning of 9/17 anyway. Just had planned that day as a MK day. The MNSSHP event officially begins at 7pm, but guests can start getting the wristbands at around 4pm. If I enter the park in the morning, and plan on going to the MNSSHP in costume, can I wear my costume then, and stay in costume through the day or are costumes only allowed to be worn that day after MNSSHP entry times ?
