Hi,I have been offered a free trip to Hong Kong. My niece lives there and needs nanny help with her 2 year old twins to make the flight back to HK from US. So in exchange for the 18 hour flight with two 2 years olds I get to see and stay in HK. I am overhhelmed at the offer. I have never travled out of US excpet to Mexico and Canada. No international flights at all. I will have to fly home alone. I am 47 and just a bit set in my ways. I am not good at getting out of my comfort zone. I am afriad I will regret it if I do not take this opportunity. Please advise on what I would be passing up or not? Thanks Sorry so long.
