Shall I have to tip tour guides and drivers after the trip?

It is customary in Asia to tip service providers such as waiters, at approximately 10%, depending on the service. Tipping is expected - though not compulsory - and shows an expression of satisfaction with the people who have assisted you on your tour. Although it may not be customary to you, it is of considerable significance to the people who will take care of you during your travels. There are several times during the trip where there is opportunity to tip the local guides or drivers we use. You may do this individually.
