How much is a taxi ride from Jeju City Hall to Lotte City Hotel??

Hello:

The two places you mentioned above are both in Jeju City in the northern part of Jeju Island. Take a taxi from the Jeju Provincial Highway Office to the Lotte City Hotel in Liandong, Jeju City. It's very close. It takes about 6-7 minutes to take a taxi. The starting fee is 2,800 won, which is about 18 yuan.

Hope this helps.
