Hi Ngo,
thank you, we were happy with your services.
however if i may say just one thing: diving in halong bay was a total waste of money for my family as it was not well organised. the site was polluted and the dive time was very short although we paid a lot of money for it. so my husband was very disappointed with the diving.
the rest was well organised, thank you once again for your help!
kind regards
Julia
