Yeah, that a special installation that you would get in your own house. Unless your friend also has this hookup (which if they do they probably need to using for themselves anyway) you have to use the special regular outlet hookup which is ~5 miles per hour of charge.
Most modern homes have a 240v hookup for a dryer or welder in or near the garage. That is more than sufficient to charge the Model S over night.
If your family already has an actual charge station they DON'T need it because they aren't about to go driving 200 miles while you are visiting, and if they are the car can be charged before you get there, or charged after you are done with Model S. It takes 4 HOURS to do a full standard charge. You can charge 2 cars in a night easy.
If your family doesn't have a 240v plug it can be installed for anywhere from $300-$1100. If you go there regularly, just pay to have it installed and it will pay for itself.
