Fees are on their website.
If you are a museum member the cost is $5.00 per person. If you are not a member the cost is anywhere from 15 to 20 per person. Buy a membership and that way you can go more than once. Fees on the site. Buy on line and skip the line at the door. Tickets are timed, but there is a ton of stuff to do while waiting. I rarely can get my grandchildren, now age 10, to leave in less than 4 hours.
Yes check website, but I think $8-10 for general admission. I believe for the Lego exhibit is extra.
