Background: I go to China a lot, but I generally exchange small amounts of currency with a friend or at local exchange places. However, I recently got a Chase Sapphire Checking account that seem to give fairly good foreign exchange rates and no ATM fee (but only 2 fee-free foreign withdrawals per month) I guess I can make 2+ withdraws and eat the ATM fee, but would be nice if I can withdraw $6900rmb (just below my bank's limit) in 1 shot at the airport. I need to pay off a friend soon and also happen to be arriving with not enough cash for taxi to my hotel either... (I usually take the metro, but I happen to be bringing 2 big suitcases and arriving at 7:30pm on a monday)

By searching, I found the following foreign-friendly bank ATMs. My question is: Can someone tell me what withdrawal limits should I expect at these ATMs (or other more advantageous ATMs)

ATM of Foreign Banks for automatic withdrawal - using foreign credit or debit cards:
South of the north walkway in the reception area of the Domestic Arrival Hall (Hang Seng Bank);
South of the middle walkway in the reception area of the International Arrival Hall (Citibank);
Next to the Hong Kong, Macao and Taiwan Landing Visa Desk in the International Arrival Hall (HSBC Bank); and
East of baggage carousel 27 in the International Arrival Connection Corridor (HSBC Bank)
