6. Hogwarts School Of Witchcraft & Wizardry (Harry Potter)
Getting into Hogwarts itself is a bit of a challenge, particularly if you're uninvited or not the relative of a student there, as its location is hidden by magic in order to prevent unwanted attention. But let's be honest, if it was real, Potter fanatics would be scouring the globe tirelessly until they found it, because who wouldn't want to hang out with some wizards and maybe learn a few tricks of the trade? The school is located in Scotland's Hogwarts Castle, and is a picturesque sight indeed, complete with baroque architecture, a loch, and as would perhaps be the most fun, a full-size Quidditch pitch (a fictional game so popular that mere muggles actually play it for real). Who wouldn't want to give Draco a smack around the face and hang out with the characters we've grown to know over J.K. Rowling's hugely successful series? Granted, short of being wizards ourselves, this one isn't much of a possibility.
