How to close
How a Silom half-day closes: one loop of Lumphini, Neilson Hays or the snake farm at noon, and only Mahanakhon at dusk. If you go up State Tower, drop Mahanakhon. Patpong waits for dark. The river at Si Phraya is another axis; if today is already the park, do not cross to ICON. Observatory fares follow the building that day.
