Neighborhood tourism
Let's start with a night in Yaowaraj Road - Bangkok's Chinatown!
Here's how neighborhood tourism works. You pick an area of Bangkok - preferably a suburb that you haven't ventured into for many a year - and you stay for one night in an expensive fancy hotel and amble around the area taking in any interesting cafes, parks, temples and street art, etc that might come your way. That's all there is to it.
