It’d be an interesting decision whether or not to return to fairytale land. Some characters lives are better in Storybrooke whilst others would want to return home. However, I don’t think it’s going to be a simple question of whether to return or not. All magic comes with a price. It would take magic to get back to fairytale land and I think the price is going to be Storybrooke.
Fairytale land was destroyed when Storybrooke came into existence. It would make sense that, in order to restore fairytale land to what it was, Storybrooke would have to be destroyed.
