This is as straightforward as it sounds, basically when you get to the Lakeside go around the road in a
CLOCKWISE direction (follow the video below).
Now there are only 24 caravans on the site, which makes it easier.
Some of the caravans are locked and some are not, you just have to go around and check each one. Just so you are aware when you try to open the caravan doors with the
button and if you have your TV loud enough you may hear a knocking noise or door lock noise when trying the door.
