I reset the Tab S. All went well though it keeps wanting a Google account log in. Is there a downside to entering my Google account and continuing setup? Or should I hand it over to the parents and get them to solve all that side of things?

you can set it up on your account for testing but it does lock it to your account, such that even after a factory reset it would only let you login using your own account.  This account needs to be removed from the device prior to a factory reset before it can be setup with another account...
