No
General admission is free; however, special events is when you need to pay. I think the best thing you can do is try to book your tickets in advance so you wouldn't have to wait in a long line
No unless for special event
No, you do not have to pay to get in. There are free tickets online, where you can reserve an entry time to get into the museum. If you do not reserve your ticket online you will have to wait in a standby line, which takes a long time to get through. Best bet is to reserve your ticket ahead of time.
You dont have to pay but you do have to make a ticket reservation online.
You don't have to pay for entrance
