Visited yesterday on foot.
I remember thinking "wow, did they use a drone?" when seeing the promotional photos for their hotel, but actually there's a convenient path on the mountain right next to it which is where they must have taken their pictures from as well 😂
At the end of 2019, this location was listed on Tesla website as having 2 chargers. But there must have been 3 Tesla wall connectors for a while, those are visible on most of the hotel pictures, including the cover picture from April 2018 on Tripadvisor.
From July 2022 to September 2023 the location was listed on Swisscharge. One of the charger CH*SWIEE129384 showed out of service for almost the entire time. All were constantly out of service starting from December 2022 apart from a few periods of a few hours each.
There's a picture on Google Maps from April 2022 showing the white Zaptec chargers already, maybe they were operated internally before enabling Swisscharge.
Now the chargers are free again. There's a sign on them saying to ask at the restaurant for activation.
