We are planning to stay for 4-5 nights in Sanya, in September. Hoping the rainy season will be over by that time. Trying to find information on cruises from Sanya, but could not find any on the web. I will appreciate any information you can share...

Can we make a day cruise or overnight cruise to Halong Bay? What are the departure/arrival times? And cost, please.

Thank you very much in advance...
