Family pass 82$, adult 26$
Different prices but worth it
I recommend you to buy the NY pass which includes this museum
Depends on what you see or purchase
On Monday is free, you have to reserve on the web page, also is included in the C3 ticket or Citypass if you want more attractions for less.
We spend about $160 online for 2 people for Liberty Island, Ellis island, 9/11 museum and ride to floor 102 of the freedom tower.
