Have your ticket printed out as your cellphone signal will be weak in this area. There is WiFi once you get to the door but the lady checking the tickets before you even get inside. The ropes wouldn’t let me pass until I could pull my ticket up, but she was letting everybody else go in front of me. So in my American accent, I had to tell her why are you let these other people go in their ticket wasn’t showing up, but you gonna make me stand here until mine actually show up to verify. After that, she let me go up there even though the people at the door were checking tickets when you have access to Wi-Fi. But have your walking shoes on and your patience in your back pocket because this museum is massive and it’s packed.
