Hotels don’t have Superchargers. They have destination chargers. EV6s are pretty easy to use, they drive a lot like a regular ICE Hyundai. I recently rented one for a week. Need an adapter for Tesla chargers, lots of hotels have both types though. I carry my TeslaTap on business trips and try to get Polestar 2s. Controls are a lot like my Volvo C40 and just feels familiar. Maybe get a Model Y for your first EV rental. They’re fun to drive but I hated having everything on the central screen. Door handles on the cheap Teslas and the EV6 I’m not fond of.

It’s a PHEV with a pretty small battery

I can turn my Samsung smart TV on & off over the network with Home Assistant. You could probably also do it with an IR blaster.

If you have an Alexa device and have it connected to Ring & Hue, you could create a routine to do this.
