Hi, they run from 11.00 am until 21.00 pm, the hotel pick up points are Amora Thapae, Imperial Maeping, Le Meridien, Shangri La, The Empress and Holiday Inn, if you are not staying at any of these hotels, just go to the nearest hotel on the list and wait in the reception, buses are every hour, so best to check with the hotel in advance. The Mall opens at 11.00 am and closes at 21.00 pm, have a lovely stay, The Mall has many places to dine and is fully air conditioned
