This is the Tulip. It's a static caravan on a private park in Ingoldmells. It's detached, so you've got your own space. The park is quiet, which is the main thing.
It's a 4 Star graded place, which is the higher end for a caravan. It sleeps four in two bedrooms. One bathroom with a shower. Everything's included - bedding, towels, the electric. There's a TV, WiFi, and parking right outside.
The living area is open plan. There's a patio with some garden furniture too. You can bring one dog.
You're about a 20 minute walk from the beach at Ingoldmells. It's sand, it's flat, it's good for kids. The water's shallow for a way out.
If you want the big attractions, they're close. Fantasy Island is basically next door. Butlin's is a short drive or you can get the bus. Skegness is about ten minutes in the car. All the usual seaside stuff is there: the pier, amusements, an aquarium.
For something a bit quieter, head north up the coast. Chapel St Leonards, Anderby Creek, Sutton-on-Sea. They're all within half an hour. Good for a change of pace.
If you're planning days out, these sites are useful: Lincolnshire Wildlife Trust for nature reserves and Lincolnshire Wolds if you fancy a drive inland.
