How to go from Grand Hyatt Erawan to Hilton
  1) The best way is to go by taxi. Taxi metered starts from 35 baht
       (US.$ 1 = 44.5 baht)
  2) Walking is possible. For me I will choose the red arrow, which is closer.
  3) You can use Sky Train but it is only one station!. Compared to taxi
      I will go by taxi. If you use local taxi, go by meter, it is not expensive.
