I actually think that Snow just wants to go where Emma goes, it isn’t that she doesn’t want to go back to fairytale land. She wants her family to be safe and together. I think that is all she is thinking about with regards to this plot, so if they decide they are safer in the Enchanted Forest then i could see them making that call.
I still think they would be safer in the Enchanted Forest all living together under one roof with guards and friends all working together. There may be ogres, but there is danger in the real world for sure. Driving in a car is probably more dangerous then ogres. And Regina can just walk in and take Henry if she wants to in the real world, at least in the other world there might be a way to set up some sort of protection or at least obstacles.
