The doors open at 8:00am but I've found visiting the show after 3:00pm is the best time to go. Stop by the Reading Terminal before hand and enjoy a great dining experience, also don't forget your camera.
I recommend arriving early. Less crowds. It becomes very busy later in the afternoon.
It opens at 8am and closes at 9. Definitely plenty of time to see everything! I hope you enjoy if you go:)
