One of my favourite Taj Mahal photos, this thread has made me go back and look at all of our lovely photos - must get around to getting them printed!
We didn't get ill either. We stayed in a lot of home stays and ate with the family, got restaurant recommendations from locals, and were just quite careful.
Not far outside of Jaipur near Amer Fort is Elefantastic, completely touristy, and expensive as far as things in India go but a lovely experience with the reassurance that the elephants are well cared for.
I found Jaipur the most challenging city we visited, I think it was the tuk-tuk drivers, they were by far the most persistent we encountered, I think maybe there's just too many of them. It does have a lot of good things going for it though, one of our favourite places was the beautiful Royal Gaitor Cenotaphs. Very small entry fee and we were the only people there (making it quite a good place for a game of hide and seek!).
Another quiet (although not as quiet as the Royal Gaitor) and beautiful place was the Tomb of I'tim?d-ud-Daulah in Agra, we visited on the afternoon after sunrise at the Taj Mahal - good time of day to go in terms of crowds/queues.
We visited Ramthambhore national park where there seemed to be a good chance of spotting a tiger, in fact everyone we spoke to had seen one, apart from us. I worried beforehand it might be disappointing for dd but she wasn't upset, we had a great time and felt like we'd been very close (plus its a reason to return one day!).
If you're flying in to Delhi there's so much see and do there as well, I loved it although I'm aware other travellers are not so keen.
I could go on and on and on but I might get a bit boring!
