So I was making a reservation for a couple night stay at the Grand Canyon next year. (Even outside the main tourist season, it's advisable to book lodgings well in advance.) I called the Best Western Premier just outside the Park in Tusayan, AZ, where they have two Tesla chargers. I wanted to make sure they were still in operation and good working order. After all, there aren't many options for charging in the area.
Generally speaking, a hotel's EV chargers are for guests only. The front desk person I spoke to said the hotel was well aware of the scarcity of EV chargers around the Grand Canyon. She also told me the hotel will accommodate ANY Tesla owner that needs a charge and not staying at the hotel. Naturally, guests get first preference but Tesla owners staying elsewhere are welcomed to use their charges if available - no charge. That's what I call a Tesla Friendly Hotel. Hats off to Best Western! Noting how things change, I would still call ahead to make sure their offer stands.
