Unfortunately, our tour to Beachcomber Island ($190 in 2014) was canceled, so we just went to the shore, to look at the surroundings.

We were immediately picked up by one cheerful girl showing us the way to a shuttle bus. I instantly suspected that something was going wrong on the way behind the fence where she was aggressively leading us and another old man. The bus turned out to be in a different place, we turned around without even listening to her objections.
In the bus, we were instructed to not join in a conversation with anyone, especially to not tell anyone our names, to return to the ship and leave cards, money, and all the jewelry in a safe if someone had the imprudence not to take it off.  
I thought I'd better get back to the library, to a good coffee and quiet work.
And we did that after forty minutes of walking around the 

city

 where we were transported by a free shuttle: this tour disappointed us. It was dirty, attractions were unsafe, the locals were annoying, and there was a real rain shower.
