I would probably go to Japan and visit a few temples, then go to China and have unfettered access to the Forbidden City, which I would take full advantage of. If I thought I could do it in a few days, I would excavate where they think the First Emperor of China's tomb is to see if there really is a landscape of China with rivers flowing with mercury. And if I have enough time left, go to Europe and see the Harry Potter amusement park there. No rides, just exploring the exhibits. And checking out every wand they have at Ollivander's. The Harry Potter thing doesn't have the same enrichment value, but seems fun.
