Memberships to Museum of Play, etc.

I know we have talked about this before.... but I can't remember.  What is the best membership to get?  I definitely want the Strong Museum of Play, but I seem to remember that there is some other place that you can be a member of for little to no more money and it includes the Museum of Play.

Also - Is there a way I can get a membership for my mom and me instead of dh and me?  DH is pretty home-bound with the baby stage, but my mom takes dd out when she is watching her.  Last year I bought the nanny pass for my mom which I can do again, it just sucks paying for dh when he won't use it at all.
