It's 8.50 for everyone over 1. It's 1.75 on family night, Thursday 5 to 8pm. If you have an EBT card it's 1.75 any day for up to 4 people.
Also a good deal is their membership. For $75 (approx), you get a whole year unlimited visits, plus free visits to partners on a monthly basis such as the GRAM or the GR public museaum, etc.
