I would also second the idea to stay in the same hotel as your sim partner.
To add a different perspective- I never met with my sim partner to prepare for a session or sit in the paper tiger. We just met for the occasional dinner. Nevertheless we got excellent grades for our good CRM. But we both were very experienced in Boeing aircraft though it was a new type for both of us. So everyone is different in how they prepare.
