We will be in Seoul Jan 2-4 and then 9-12. Most of the time there will be 4 of us (sometimes 5)
How much should we put on a card? Also, this card is ONLY for Seoul? Can we use it for the airport to our hotel or vice versa? (we'll stay in Mapo-gu two nights and either Myeongdong or Jongno for 3 nights then go back to the airport).
We do plan to visit Hondgae Jan 3, and then around Myeongdong and Jongno Jan 10, 11 and Gangnam at some point as well.
We will also take a train to Daegu...do these cards work in other cities? Or for the train to other cities?
Can taxi's take 4 ppl? Is that the max?
