Delhi, Jaipur, Agra, Varanasi tour group recommendations mother and adult daughter?

Would anyone recommend a tour group with a company for me (31F) and mother (65F) to see the Golden Triangle, India. We would also like to see Varanasi but do not want to take any sleeper trains. My mother would like high end accommodation if possible. Thanks!
