"Once upon a time" ... rather than in actual times, this how fairy tales begin and you can time travel at any magical era or place you wish. Let's face it the fairy tale it is only the excuse in order to jump into another reality, full of princesses, kings and queens, trolls, dwarfs, fairies, dragons, unicorns, mermaids, talking animals, small people with legendary powers and many other wondrous characters. Visit any magical place possible, like deep ocean castles or get lost in a labyrinthine and still come out alive! No, in this case you are not human any more, you are gaining mystic powers and you follow your fairy tale heroes around at any hardship or mission. And guess what? The fairy tale endings will never disappoint you like real life does, because ... "they all lived happily ever after"!
