The Taj Mahal is a massive, beutiful place... surrounded by people with ugly hearts. I am glad I went there, however, I think I would rather go there on my own with no other people.
Inside the Mosque part, we spent the whole time running away from this man who wanted to make himself our guide. 'tell us facts now, tip me later'. We dodged him and disappeared into the crowd. However, this means my memories of the insides are of avoiding an annoying man, not of being in one of the wonders of the world.
Very easy to think the world will all be peachy and sanitised. In reality, it is a mess, and people will make money off the back of anything.
