The main attraction is of course the turtle viewing tours. Despite some reviews indicating these were insensitive, poorly run etc, our experience of these was very good. The evening tour was a group of 20, but we felt the guide managed it very well, taking care to interfere as little as possible in the amazing spectacle, often using sub-groups etc. The morning tour was quieter but definitely do both.
Hotel itself is fine - nothing special, but does the job well enough. It looks somewhat dated to be honest, but the rooms were clean and bed comfy, which is all you need here really. We found the evening food to be decent and very good value. Breakfast was not so great.
We visited in September on a weekday - so I can't speak for what it is like in other times / on weekends when it may be busier.
