Hi, I've been to Halong Bay once and it was about few years back. I will return Hanoi and intend to visit Halong Bay again. I joined a 2days 1nite package with 8guests only during the visit. I can't recall how much the exact price of the package, less than usd100 if I'm not mistaken. It was recommended by lonelyplanet guidebook last time. I would like to join the small group tour to halong bay again this time, could someone here kindly recommend the tour agencies here. Thanks.
