Convenient service. Did not realize there was a second step of check-in after dropping off the keys at the appointment time which created a further delay as I had dropped off the keys and went about my work day and was not monitoring my email for the second check in that was needed until two hours later. Also, was a little disappointed that my keys were 20 minutes late getting dropped back into the drop box after my expected end time, it caused me to miss my children's school bus pick up. Next time I know to set my work end day for an hour prior to when I need my car back to allow for delays I suppose.
