Only did the one night cruise. Was very pretty, but after a certain point, you just see mountain and then....another one...and another....all the same.Sounds pretty good. Curious of your impression of Halong Bay.
Cruise ship was nice...kayaked and swam around that was nice. Water was very warm.
Meant to visit a cave but the tide was too low so the boats couldn't cross over.
Not sure I'd do it again though, was fun and romantic with my girl, but am much more of a city boy.
