In September I stayed at several Hilton properties that had Tesla Level 2 charging, at 208 volts. I do not recall the amps, but they charged my MX overnight. There was no charge to use the chargers, and they were not the expensive Hilton brand, one was called Homewood Suites.
Is it becoming common to have a fee at hotels?
When I booked the hotel I made sure there were Tesla SuC nearby in case the hotel's L2 chargers were occupied when I checked in, but at one hotel both stalls were not occupied, and at the second hotel only one of the two stalls was occupied, so I was good and had a full battery the next morning.
