“My husband and I went on a 2D1N cruise on board the Pelican. I was very impressed with its amenities and the service provided. We had the Royal Suite with an ensuite bathroom, a magnificent view of Halong Bay from our very big windows and a private door which leads to a private deck. We were served lunch and dinner (7-8 course) on our 1st day and breakfast (buffet) and brunch on the 2nd.

We were taken to Luon Cave and Titop Island on the 1st day and Surprise Cave on the second. Passing through Luon Cave in a small boat, we reached a lake formed by an enclosed group of limestone mountains. We were fortunate enough to be greeted by the monkeys that live there which came down to have their photographs taken…
