OP here. DD and her boyfriend are back in China after ten days in India. They had an incredible time. They saw many historical places, slept in the desert, rode camels and even had a quick trip to a hospital. Nothing serious, just gastro issues. My dd sent me a text that said “Just so you know Mom, India’s hospitals are easy to use.” They had no other trouble and are really glad that they went. Thank you all for your advise, even if it did make me nervous. I shared your wise words with my dd and I think it got her and the boyfriend a little more on alert. They did hire drivers and guides ahead of time (thank you, tripadvisor). So again, thanks!
