Being welcomed with “Sorry, you’ve got the crappy cabin” was not a promising start.
True enough, cabin 15 was indeed very dated and really in need of replacement. I’m not sure why we were put in it though. While all the flash units on the beachside did seem occupied, the rest of the park, and most of the other cabins, appeared empty.
My advice would be not to book through a third party website, but book directly with the caravan park, and make sure exactly what you’re going to get!
