Worst experience ever. Departure to the island was late - and they drove us to another pier (NOT serendipity pier!) which took about 45 mins, with lots a bumpy roads, to a pier filled with rubbish and plastic bottles. My booking was 9am but we boarded the boat only at 1145 or something.
The boat back was supposed to be 7am per the booking but when we reached there, the staff told us there is no 7am boat, and there is only one at 845am. Of course, rude staff. We waited and waited and the boat only arrived at 945am, and ferried us back to the pier with all the rubbish (NOT serendipity).
Terrible experience and I have no option of giving it 0 stars, else I would. Highly NOT recommended. Also not cheap at all. There are way better options for pristine beaches around the region. Do not waste your time at Sihanoukville/Koh Rong. From the reviews posted a few years earlier, nothing has improved
