Does Derek's place provide shower or beach towels?
There is a communal bucket shower, which is a big barrel and you have a bucket to scoop the water out and over you. Our kids thought it was really neat. You do get towels in your cabana. We stayed in the Bottle House which has its own private bucket shower and the Beach House has it's own private one as well.
Since then, several of the bungalows have had toilets and showers installed. That being said, you must still scoop bucket but in privacy of your own bungalow. It was our honeymoon so that was nicer than group communal shower, but that was clean and nice too (just not for honeymooners perhaps).
