Yes, it makes no good sense, or business sense, to be so strict with the timeline immersion. After the movie, that timeline doesn't flow well anyway. As Joe said, just let it be FUN. That's the secret to Potter. Whoever is responsible at Disney trying to be so strict with the Batuu immersion stuff, is just being 'stupid'. A little crass, but that's the best word to describe the stubborn stance. Damn, put all those great Star Wars characters in the land. Why hold back now?
