Is it better to travel from Beijing to Seoul with a group or by yourself?

Conscience advice, free travel is very tiring. I booked a plane ticket six months in advance when I went to travel freely, and the hotel is also a cheaper youth travel. More than 3 thousand, almost 4 thousand, just this ticket and hotel It is estimated that it will not be cheap during the winter vacation. I tried to travel freely and join a group in Korea. Last year, I went to Seoul, South Korea for five days with my sisters. The round-trip airfare plus accommodation mentioned above is more than 3000 people, not counting shopping. I live in a youth travel agency with average conditions. Another one is to accompany my mother. South Korea is a group that travels with China and Singapore in their newspaper. Seoul plus Jeju ***5 days, the tour fee is 3980, and it costs nothing except shopping. It's quite comfortable to stay in an apartment hotel. The group meal is not bad, and there are some special dishes, such as ginseng chicken and Ding Han food. Duty-free shops like Lotte and Myeongdong Shopping Street have plenty of time. Unlike many people who say that it is unpleasant to restrict group tours, we have never met them, and we are still very harmonious these days. They also have a semi-free tour group, which has a team trip and a certain amount of free time, which is quite intimate.
