Model S makes use of SAE J1772 only via an adapter, and it's not clear that the average Model S owner is going to make frequent use of J1772.
Tesla is recommending that Model S owners either install an RV style 50A 240V outlet in their homes, or else install a charging station that has the Tesla connector that is currently only used on Model S. The Superchargers also do not make use of J1772.
If hotels end up installing J1772 and not Tesla charging stations, then perhaps Model S owners will use the J1772 adapters at hotels.
