I will travel to Korea with my classmates in the summer vacation, about a week. I will go by myself, not with the travel agency. ...

If you go to Korea by yourself, you'd better book a hotel in Korea first, otherwise it will be expensive to book a hotel when you arrive that day. Ordinary guest houses cost 40,000 to 50,000 won a night.

Book your own air ticket+hotel first. If you are a student, you'd better go to the subway station or some 7- 1 1 shops in China to buy a card such as Yangchengtong or Hong Kong Octopus. South Korea's subway and bus are very cheap, subway 1000 yuan. As long as you don't leave the station, you can sit there all day. Korean subways basically have Chinese signs. You can get free maps from the Immigration Department or the Korea Tourism Development Office in Seoul. If you still don't understand it at home, you can consult the staff inside, or you can contact the staff in advance on the website of the Korea Tourism Development Office now.

In addition, generally speaking, food eaten in South Korea is more expensive than food eaten in China, because consumption in South Korea is high and their wages are high. Compared with domestic food, except for houses, the quality of other foods is higher than domestic food. A flexible Shiwo bibimbap costs more than 5,000 yuan, but when I arrived in Korea, I had to eat a Korean buffet teppanyaki. Some shops only 10000, want to eat something better, 20000-40000. If you want to change won, you'd better go to the Bank of China in the provincial capital, and banks in prefecture-level cities have no change. Or go to some banks in Hong Kong and Macao for exchange. It is very expensive to change it when you arrive at the airport or the Korean airport. In addition, you can bring a credit card (dual currency card) in US dollars and RMB, which is not accepted in ordinary snack bars. There are also tickets for scenic spots and some discounts. It's best to buy a set meal at the Korea Tourism Bureau first, and then choose tickets, and there will be a discount.
