I just posted this question to Hotels.com. I think it would be a good idea for everyone to post something similar (please don't copy/paste what I wrote) on all the hotel searching sites. I think that if they get enough requests, they will start to ask their hotels if they have facilities, which may lead to the hotels installing them. "I need to find hotels with facilities for charging my EV (Electric Vehicle). This is becoming more important for those of us that drive cross country. Please add "EV Charging" to the list of checkboxes in the search criteria, and ask your hotels to respond, so that we can find the hotels we need. Thank you."
