Per one customer who booked the Ha Long Bay 5-Star Day Cruise With Buffet, Kayaking, and Swimming, "An absolutely surreal experience, sailing in the Halong Bay on a cloudy day, which made the experience just out of this world. A fantastic tour guide, 'Harvey,' and a great driver. A great ship to cruise in; superb food at the lunch buffet. And the cruise among the islands themselves. Just magical. I could not have spent a better day. "
