Asain people are very hospitable and will probably be happy to show you around, sorry didnt read this posting before. Plenty of ATM machines everywhere if you need more funds. Change some money at the airport to tip taxis, porters etc.You can change some at UK airports, they tell you its illegal to comply with regulations and then give you the currency !
always tip the "little man" eg porters, bell boys etc they earn such a pittance and take it straight home to help their families.Try the rickshaws instead of taxis, they are great fun.
enjoy your break, are involved with call centres ? I hate them.[sorry]
