Bangkok is a big city that offers several activities to both locals and visitors. However, many activities are outdoor activities which cannot be done on a rainy day. Besides, in Bangkok when it rains, usually it rains hard. So, it is difficult to go outside. Many people who live in Bangkok choose to stay at home and take a rest instead of going outside. Well, I do understand a tourist. Who else want to spend time all day in a hotel/ hostel during vacation?
