<< They can only bring guests by:
a) adding additional Platinum cards to their account, >>
I know what you're try to say, but to clarify: adding additional Platinum cards doesn't enable guesting privileges - rather, the cardholders of those additional Platinum cards get (non-guest) entry for themselves.
