My 11 y.o. daughter and I must travel from Guilin to Hong Kong on the morning of 7/2. I've priced the flights from Guilin to Hong Kong, and it would cost about $600.00 for both of us to fly via Dragon Air. Is there a more economical way? The flight from Guilin to Guangzhou is not nearly as expensive, and we would be willing to travel by train or boat to Hong Kong from there to arrive before 2 pm. Any recommendations would be appreciated. We would like the travel cost to be under 300.00 USD total for us both.
