Any idea of the BTS operating hours ? We have been looking for that in its web but cannot find the information. Please also advise which is the best value-for-money BTS ticket for a 5-day trip in Bangkok - 1)stored-value one valid for 2 years of 100 baht which its value can be refilled, 2)one-day unlimited ride ticket of 100 baht and 3)ticket for 15 trips (from the web it's said that for some distance/trip longer than the distance permitted for this ticket, cardholders have to pay in the additional fees at the ticket-office. Any idea about this restruction ? Which of the stations are normally not covered in this 15-trip ticket ?) Thanks to anyone who helps !
