They don't work as rentals anyway. Cost of operating goes out the window the second home charging isn't used.
Again - subsidized charging can change that dramatically. I don't know if I'd really want to park at some locations that provide subsidized charging just to save on that. If I'm renting a Tesla and there's a Tesla Destination Charger at a hotel I'm staying at, that clearly changes the cost vs convenience dynamic.
I was thinking that Hilton's buildout with Tesla's Universal Wall Connectors is going to make things easier.
