Pick one
How the day stops: enter only one of the three night markets. In Chinatown, MRT Wat Mangkon onto Yaowarat, one stall, leave by the same station. On the west bank, after Lhong or ICON in the afternoon, one round and one stall at Asiatique, then the boat back — do not return to Yaowarat. Ratchada enters by the Cultural Centre; afterwards the hotel, not a temple. Khaosan is a night street, not a fourth night market.
