Are there many people going to Hainan during the eleventh period? Was it hot then?

The Eleventh Holiday is now a rare seven-day holiday. There must be a lot of people, and at that time, air tickets and hotel prices rose sharply. If you don't book in advance, a better hotel may have no vacancies.

Hainan is still quite hot during the National Day. It's over 30 degrees during the day, and it's slightly cooler in the morning and evening.
