Yes, GreenLots has an awful map because you can't filter by plug type, and even if you could, all of the U-GO DCQCs are set up incorrectly. They all state they are "240 AC" stations under Type, and then the description says Level 3.
As far as what the hotel can do to make the QC a success...
First, they must ensure the signage is adequate. The best option is signage that clearly states the spots in front of the QC and Level 2 stations are for Electric Vehicles ONLY While Charging, all others TOWED at owners expense. In addition, the lines should be repainted green. The "Electric Vehicle Charging Station" signs that list no parking restrictions are not adequate.
Second, they should ensure that all of the hotel's maintenance employees, even the ones that work overnight, are trained on how to reset power to the QC from the breaker. If there are filters that require regular cleaning, they must be trained on that, too. The front desk staff should be trained to call a maintenance employee if a driver comes inside to ask for help in the event of the QC malfunctioning. The worst thing a driver can encounter (after being ICEd) is a broken QC that they are relying on.
Finally, they should post a sign on or near the QC inviting customers to come inside and use the restaurant/lobby/bathrooms/whatever, but remind them to move their vehicles when charging completes to avoid being towed. Maybe they would consider offering a discount in the restaurant to those who mention they used the QC?
