This is Détendez A La Côte, it's a static caravan on a park just outside Skegness. The name's a bit much, I know, but it's what it's called.
It sleeps four. Two bedrooms, one bathroom. It's got a 3 Star rating, which is about right. It's clean and everything works, but it's not luxurious. The layout is open plan so it's all one space for the kitchen, dining, and sitting area.
It's on a proper holiday park, so there are other vans around. You get your own bit of decking with a hot tub. Parking is right outside.
For facilities, you've got a TV, WiFi, a shower, and bedding is included. One well-behaved dog is allowed.
Skegness itself is about a ten minute drive. You know what it is: a proper seaside town. The beach is big and sandy. There's the pier, amusements, fish and chips, the whole thing. Fantasy Island theme park is just down the road if that's your sort of thing.
If you want to get away from the crowds, the Lincolnshire coast path is good for a walk. Andioles Wildlife Centre is worth a visit if you like birds. Further inland, Gunby Hall is a nice National Trust house and gardens, about a twenty minute drive.
