My opinion - I think any kind of cone or barrier is a terrible idea. Many will ignore it anyway, but I for one don't want to;
Arrive at charger
Stop, get out of the car (possibly impeding through traffic)
Move cone out of the way
Back into charging spot
Complete charging
Pull out of charging spot
Stop, get out of car
Replace cone
Go on my merry way.
It's bad enough to have to do all that when the weather's pleasant. Miserable sequence of steps if it's raining hard/snowing/strong winds/just plain coldcoldcold.
Agreed but given a choice between having no access to the supercharger and having to perform those steps, I would choose the cone situation. I don't know what other approaches they have - clearly the hotel will be reluctant to tow anyone. Maybe if they only coned off a couple of the bays so you could just drive in unless the drive in slots were ICEd and then you moved the cones only if that was all that was left. Unfortunately I guess that would probably make the other spots look like they were fair game.
