I recently stayed at SF Marriott Marquis and was extremly frustrated by the check in/out process for elite members. They assigned one front desk person for the elite members lane and thus the wait was much longer.
I am wondering if anyone else has experinced this. My recommendation would be to copy the process for the premier access lanes at the airport. If any front desk staff is available and if there is a customer in the elite member lane, then they should have the priority over the non elite members who are also waiting for check in.
