If you "stay with family" I assume this is a few hours or overnight. Even slow charging from a regular outlet gives enough over night or a 6 hour stay. In Europe a regular outlet can give 3-4kW, so 6 hours is enough to go another 100km.
At work they installed a lot of 11kW chargers. Sure - some might need them, but most people would be fine with topping up their cars every day on a single phase charger. You park there for 6-8 hours, even at 3-4kW that would be enough for a daily 200km commute (which is rare, that guy can go to the 11kW charger).
I stayed in rural Italy with really old crappy electricity. Even there I could hookup the car on single phase at 1kW and keep charging. Two days later it was full again.
