Overall, this was a great service. The location where I parked was easy to access and the customer service was friendly. I was a bit confused because I thought I paid everything online, but was asked to pay $3.55 in person, which was written on my email. Thankfully, I had cash or it would have cost an additional $7 to process the credit card on site. When I returned, I did have trouble contacting the pick-up. I called twice and let it ring 10 times each time, but didn't get anyone to answer until my third call. In between, I did call the customer service line for book2park and they were helpful.
