I went in November and it was a bit cold. I also participated in the recommended day trip at my own expense. According to the leader, I played Jeju Island this time and didn't have to go in the future. Attractions and shopping are good. You can fly to Jeju Island in 2 hours, which is closer than domestic. Meals can be full, and you will not be hungry on the journey. Basically, I am very satisfied, I still like Trip.com, all of them have small groups of less than 16 people, and they are more comfortable to play.
