When I get my Model S in the Spring, I plan to take my holidays and drive across the country (Canada), culminating with my friend's wedding in Nova Scotia. I've already got a rough draft of my route and have selected EV-friendly hotels with on-site charging to spend each night. Something got me thinking though, what is the proper etiquette for using a hotel charger? I guess my original plan was to check in at the hotel, grab something to eat, plug in my car, and head to bed for the night. My car would occupy the charger from ~10pm to ~6am whether it was charging or not. Now, I'll probably be pretty low on power when I roll in to town and will need most, if not all, of that time to actually charge, but what if someone else checks into the hotel late and needs the charger? The chances of this occurring at this point in time are very rare, but I don't want to be the jerk who blocked the charger all night when someone else needed it, either. What is the proper procedure here? Do I have to wander out and move my car at 2 or 3 in the morning if it happens to finish charging early? Do I leave a note with the front desk with my contact info which they can give to someone who inquires about using the charger? Do I play the odds and just not worry about it?
