I get claustrophobia in crowded museums. 50 years ago bankers got Election Day off while few others did. I would spend a lonely hours wandering thru The Met or Guggenheim. Then we last that day to MLK day and museums are all closed on Mondays. Alas.
If you can escape from the bars and baths of Bangkok for a bit, I commend the Jim Thompson House Museum. He, of the silk business, collected Thai buildings, ceramics, furniture, etc that he assembled into a magnificent estate in the middle of the city. It’s now museum and oasis of tranquility in that bustling city.
