My grandmother did the same thing in the 80's. She visited distant relatives in Sweden, went to the Holy Lands, Germany, etc. The thing was, she was terrible at directions. I think in Egypt she left a restaurant by a different door than she entered by, and started wandering down a back street looking for the bus. It wasn't a very friendly place, and the tour guide had to go chasing after her. Another time she went with a new camera, and held it backwards the whole time, taking shots of her nose and face. But she was unfazed, and would save up for her next trip.
