Do u have to pay to get in the museum

There is a few yes

I went last week. $20 for Los Angeles resident.

20 to get in. Free if you buy annual membership. 30%off entry if you are accompanying a member.

I think it was $20 for non Los Angeles county residents, $10-15 if you live in LA. Well worth the cost as you can spend an entire day there.

Yes but I don't know the price

Yes
