Emotion Junk Cruise

Hi

i was looking to book the Emotion Cruise for 3days/2nights and have been given a reasonable price from the following tour company;

Halong Luxry tour also known as Vietnam trip advisor and run by

A Chau TTD Co., Ltd Address: 56 Ma May St., Hoan Kiem Dist., Hanoi with International Tour Operator License 0752/2007/TCDL

Has anyone ever heard of them and are they a trustworthy and reputable company.

Also has anyone stayed on the Emotion ?

Thanks
