My flight arriving at 6 pm to Hk, how can I go to Sofitel Royal Lagoon Dongguan, Dongguan

There are many shuttle bus to reach Dongguan directly, but you only can take the shuttle bus to reach Exhibition International Hotel, which is close to your hotel. The bus fare is around 160 to 200HK$.
The last bus to reach the Exhibition Internationl Hotel is around 18:55. Upon you reach there, you can take a taxi to reach your hotel directly.
It is hard to find the Indian food restaurant near your hotel, because your hotel is in a park. It is suggested to ask the hotel staff directly. As far as I know, the western style food is served by the hotel.

Thank you Monica, I need to know what is number of shuttle bus to Exhibition Hotel?
do you have time schedule from HK airport? Please let me know Thanks

There is no certain bus numbers for those cross-border buses and all those buses can be found at the Coach Station of T2.
The buses to Dongguan operate from 7:10 to 20:30 everyday and the exact timetable can be found on the offcial website of HKIA.
