Seoul Metropolitan City has recently added half-top double-decker buses to their fleet. The new buses have a total of 65 seats with 45 being on the second level; the first 20 seats are covered with a glass ceiling while the remaining 25 seats are traditional open-top seats. This half open-top combination is perfect for those who want to enjoy a wide open view throughout the year, as the existing open-top buses were not ideal during the cold winter and the scorching hot summer.
