Is it easy to buy tickets for holidays in Dongji Island? What if I can't buy it?

You'd better buy it on Taobao first. Tickets are not easy to buy, and sometimes you can't buy them in the queue in the early morning, especially in the peak season. Just be prepared in advance.

It's still easy to buy in the off-season. Although there will be more flights in the peak season, you must buy them in advance, otherwise you may not be able to go.
