To sum up, Las Vegas and Seoul are very different from each other in three points. First, Las Vegas does not have seasonal differences except the summer, but in Seoul, each season has different weather. Second, Las Vegas has a terrible public transportation system and good road system; on the contrary, Seoul has a convenient public transportation and bad road system.
Third, tourists like Las Vegas’ huge scale and brilliant idea of artificial attractions, while people who visit Seoul like historical building and personal mood of the city. Although they are very different, if people visit them, they will love the cities.
