I want to purchase memberships for several different families. How can I do that on the website? I will need confirmation for each family.

I know you asked about doing it via the website, but it would be better to at least call and talk to the Zoo staff for clarification.

You can buy separate memberships online with separate transactions

Best Idea would be to call the officer

I would call the office and let a real person help you. They are happy to help

Yeap
