Three hours and the cars will be nearly dead. And the hotel will not have a charger, not for all of us. So we are going to be up all night at commercial chargers, reducing our sleep time before our first meetings from a few hours to zero. And that is if we can find working commercial chargers. The UK is notorious for needing various apps for parking/charging. The headaches are just not worth our time. Maybe if we were on vacation, but this os work.
