<p>Haven't been to Africa, but our son did a study abroad program that went to Hong Kong and I don't have financial tips for HK, but will note that the highlights of touring there were the Peninsula Hotel's high tea (has a high price, though, I will note) and seeing the view from Victoria's Peak in both the day and night (so urge her to make the trip there twice, even if on the same day). The skyline in HK is the nicest I've seen anywhere in the world. She should have a great time there.</p>
<p>I am thinking we used a credit card to pay for the Oriental Pearl Tower in Shanghai (and got "Shanghaied" as nobody spoke English there to explain how long the wait to the top was and the line was worse than at Disney World in winding around indoors such that you had no idea how close you were getting - it took us HOURS to get up part way and then we had to give up as we had a program with students in Shanghai to attend that night, and you don't even want to hear about the taxi nightmare coming back from the OPT). I am pretty sure we used credit cards in Beijing with no problem, and I know I got money out using my credit card at an ATM no problem (still remember the soft serve blueberry ice cream and green tea ice cream we got just after using the ATM at a mall; the blueberry was excellent, but the green tea wasn't so hot, no pun intended).</p>
<p>I all also pretty sure I used a credit card with no problem quite a bit in Hong Kong. But credit cards CAN and DO get "eaten" by ATMS, so anyone traveling should have at least two if not more. Our son's gotten eaten by an ATM in Lithuania last summer, and someone on his study abroad gotten eaten at an ATM inside a monastery in Taiwan, of all places. You ideally should have one in a safe in your room and another in your travel pouch under your shirt and another in a pocket or fanny pack, seems to me (and have all the bank card information in the travel pouch and safe and with someone back home should you get robbed).</p>
<p>Everyone in our family has their own credit cards so it is easy to track who has spent what. Our son has a credit card for business expenses (which are reimbursed by MIT now, but was used for figuring out his taxes back when he had his own businesses) and one for personal expenses (like his treating us to dinner last night and my parents to lunch today in honor of Father's Day), and I feel that's also a good thing for people to get used to doing early on.</p>
<p>Also tell your children to never put the passport in a place where it could be easily forgotten, such as an airport bin or the seat back of a plane (a student on one of our son's study abroad programs in France did that and thanks to the Honors College director being fluent in French, he was able to get him and the girl back on the plane to retrieve it about 30 minutes after they had left the plane, but it gave everyone a scare that she and the director were going to miss the connecting flight).</p>
<p>Our son has been to 30-some countries now between business and pleasure and has never used traveler's checks. I used to use them, but came to find credit cards more the way to go. To this day, I have no interest in debit cards (and indeed canceled my bank one sent to my house that I didn't request just this morning). Our son has been responsible in his charging (has had credit cards since he turned 13 and starting taking business trips on his own; is 16 now), so we have trusted him to not "go nuts" on purchases. After all, he knows he'll be paying the amount in full each month from HIS savings (as we made sure he had thousands in savings before he got his first credit card and he's never had a limit anywhere near what he has saved, which is enough to buy several cars at this point). If a kid isn't mature enough to not go overboard on spending, are they mature enough to go abroad? That's not a rhetorical question, mind you, but just one to discuss/think about.</p>
