Sunday is my son's second birthday. my only day off is Saturday. I was wondering how much it is per person to get in?

Save your $20+ and go to a real aquarium. This one is meh at best.

Also for the month of June 2018 of you are a annual member of the Norfolk Zoo you get in free (equal membership from the zoo) at the aquarium. Since I hold a membership for my husband and I plus one child we plus my niece got in free.

Depends on what you want to do they have a combo that includes the museum and a movie for over $20.00 and the other prices run about $8.00 and up
