Is their a deal we can get for all three museums for a family of four?

Check website

The deal for all three is the best bang for your buck..and it's worth it

I know they have a deal for all 3 per person but not sure if they have a family deal. The deal for all 3 is about 10 $ more than a single entrance and you don't have to enter all at the same day.

Yes, I've seen the packages and you should be able to, check online first
