Staff was great, helpful
I was surprised to find no rental counter at Windsor station, just a video kiosk marked Discount (not even Eurocar). After calling, it took 20 minutes for an agent to arrive to pick us up and drive us another 20 minutes to the rental counter, where we took another 20 minutes to finally get the car and be on our way. That was nowhere advertised or stated, so it came as a surprise. As a minimum, I would suggest their confirmation email ask us to call 15 minutes before arriving so the shuttle can be there. Or they could monitor the train arrival times and just be there when our train arrives. Then you need to drop the car to the rental office over an hour before the train. Something to keep in mind.
