Thailand tourism, when is there more people on National Day or Spring Festival?

If we only look at the number of people, there must be more people during the Spring Festival, because National Day is only a holiday in China.

Since the poster wants to travel, I think it would be better to go during the Spring Festival. The average temperature is 19℃~26℃. Although it is called "cool season", the temperature is not low. At this time, Bangkok, the Buddhist capital with many ancient temples, Pattaya, the "Oriental Hawaii", and Chiang Mai, the "Rose City" all have the most beautiful scenery.
