My dive buddy just wanted to be on a Siren boat and now I know why. The boat was very nice, with spacious cabins and ensuites and the staff was so great at taking care of us.
The diving was good, including whalesharks, thresher sharks and this one dive with a huge school of sardines.
There were just about as many crew members as divers and they completely spoiled us.
I ended up getting an hour-long massage nearly every day on the yacht.
I will definitely be back.
