We are two women in our 50's arriving Delhi beginning Nov for just over a month. Had planned to take the train and buses but after reading all the posts on TA wonder whether it's more advisable to hire car/driver/guide and if so should we try and arrange from this end or...? Are all of Agra, Varanasi, Jaipur, Rathambore, Pushkar, Udaipur,Jodhpur (not in the thick of things),Jaislmer, Bikaner, Mandawa too much, which to leave out? We want to leave time to visit a family I sponsor in the Kerala area and possibly do some volunteer work then spend at least a few days in Goa as we're booked to fly home from there. Any input would be greatly appreciated.
