Does the mommy and me passes include the admission for both the adult and the kid... I see it is slightly higher than regular admission but not close to the price of the 2 admissions together?

According to their site "Receive 1 adult general admission ticket and up to 4 children's admission tickets for just $41.95." That's a pretty good deal

The me and Mommy ticket deal is a great deal. It is for an adult and up to 4 children under the age of 5 and below. It's only valid until 11AM.

Have you tried city pass to see if you get a better price if you want to see more than one exhibition. I don't know know cost of momma and me. Or try Groupon.
