Writing a book about traveling alone is not as much fun as just traveling alone. I have to keep track of all the nifty things I do and all the great people I meet.Then I have to turn my mental chaos of events and people into writing that will be helpful, interesting, and worthwhile. So, today, after spending two days at the World Travel Market (the largest travel trade show in the world) I treated myself to tea at Harrods and a ride about town in a double decker bus.
