A Review of Similan Quest Liveaboard

We were on a 4 day/3 nights trip with Similan Quest. Everything regarding the booking was smooth and easy, and our questions were answered quickly.
The boat is well equipped and comfortable. It's not a luxury boat, but we knew that. Food onboard was good and standard quality. The crew were friendly and there was a nice feeling onboard. Our cabin was small, but we had what we needed. Shared toilets and baths was clean and handy. The only reason we are not more thrilled are two things: We still think the price was a bit high compared to liveaboard elsewhere, but that's apparently the level at Similan Islands. The other was a bit of dissapointment regarding the diving experience. The instructor did what he could, but we had expected the dive sites to be more spectacular to be honest. But maybe we were just a bit unlucky?
