A good reason to catch up with Dr D, Mrs Dr D and Dr D Junior . The train into Hong Kong is not too expensive and you can leave your carry-on stuff at the airport for a reasonable fee. just note that they charge per item, so get it all into one large bag rather than several small ones. It was cheaper for us to purchase a large soft bag at the airport and stuff three kids backpacks plus a few other things into it and just leave a single piece there for the day.
