member areas Member Spaces for young children. Looking for advice.

Site URL: https://www.artlytherapy.com/

My client would like to create a member area for primary school children.

Having individual signons for each primary student will be an administrative headache. 

The idea is the school pays for a membership by class.  Then the primary students of that class log in using the class userid and password.

Does anyone see any issues with this plan? Any thoughts?

Thank you in advance.
