I would go through the Narnia door. Narnia is like the only place on there I recognized other than Hogwarts and it would most likely be the funnest. I wouldn't know what to do there. I could do whatever I want whenever I want so that'd be cool and I would have nobody to tell me what to do. I could possibly discover new things or animals there. I've never seen the Narnia movies or read any of the books but it sounds fun.
