How much is it to get in? I have a 4 year old, 2 year old and 3 month old.

5 dollars a person. I believe a year and younger is free. It's a great cheap fun activity for kids

$5.00 a person. I dont recall what age it is to get in free.

$5 but under 1 year is free. They also have annual membership deals that might be worth it if you plan on going regularly. For 3 named guests, it is $55/year

I believe it's $5 per person ages 3 and up but I would call to verify
