I have been there quite a few times as I took members of my family including my relatives who visited us in Bangkok to see the Grand Palace. Besides, as a part of the induction program for new members of our team, I used to take them to the Grand Palace.
The Grand Palace can be reached by road or by waterways on the Chao Phraya river. An ideal tour is to reach the Grand Palace in the morning. Go around and view the spectacle till lunch time. Then take a speed boat ride on Chao Phraya to visit the floating part of Bangkok – a part of the city with no roads and only waterways for communication. Remember, Bangkok is also referred to as the Venice of the East.
