Upon arrival at the Hong Kong International Airport, you may want to change some money to pay for transportation to your hotel and for tips. However, refrain from changing all your money at the airport because you can get a much better exchange rate at one of the local banks. Most likely, there will be one near your hotel and close to the exhibition centers.
Most daily expenses can be paid by credit card, which is exchanged at very close to the bank’s exchange rate.
Before you continue with your trip to China, you should also exchange your foreign money into China’s RMB in Hong Kong because it is more difficult to find a bank outside your hotel inside mainland China. Hunting one down will cost valuable time. Keep in mind that hotel charges in China can be paid by credit card. In other words, you may not need a large quantity of RMB to pay for your expenses.
