Our guide, May, was outstanding. She worked easily with us to plan a full day tailored to our age and lack of sleep (jetlag).
For US$104 plus minimal transportation costs, May guided us through an extremely crowded Grand Palace, a sprawling temple complex (Wat Pho), and the Jim Thompson House.
The day was bloody hot, and May managed the logistics perfectly so that we were able to take a lot in in spite of the heat. She was also a delightful person to spend time with.
