There is the Inter-stake center there and a very nice visitors center,but when you say family room for people from out of state, what are you actually looking for? Young children who need to be monitored? Nothing available. Non-members who can take care of themselves but don't want to be bored? The visitor's center is perfect and has a beautiful view of the bay area.
Best to call the Temple
There is a church building on site but not sure if its open to have children watched there.
