After dark
Use Khaosan after dark. Phra Athit's bank and Phra Sumen are the quiet edge of the same strip, and dinner can stay there. Do not turn bars and travel agencies into a list. Eat, then stop. Do not walk to the Golden Mount after midnight.
Where not to continue
Where not to continue from Khaosan: Chatuchak at midnight, the dawn's first stop, a Thonglor restaurant, the ICON mall. The boat at Phra Athit is how you leave, not a tool for joining three districts. If the palace is on the trip, give it another morning and enter from Tha Chang.
