Hawthorne 19 is a lodge on Westfield Lakeside Park, near Fitling. It's a modern, single-storey place, detached, so you've got your own space. The park itself is quiet, mostly fields and a couple of fishing lakes.
It sleeps four in two bedrooms. Both have their own bathroom, which is handy. One room has a double bed, the other has twins. They both have doors straight out to the garden. Everything is on one level, so it's fine if you have mobility issues or just don't want stairs.
It's got an open plan living area with a kitchen at one end. The kitchen has a dishwasher and a washing machine. There's a TV and WiFi. Outside there's a patio with a table and chairs, and a hot tub.
You can bring one dog. The garden is enclosed but it's not totally fortress-like, so keep an eye on a real escape artist.
On site, there are the fishing lakes you can use, and there's a cafe that does breakfasts and lunches. For anything else, you'll need to drive. The coast at Tunstall is about ten minutes away by car. It's a good beach for a walk.
If you want a day out, Burton Constable Hall is close by. Spurn Point is about half an hour's drive. It's a long spit of land into the Humber, good for birdwatching and a bracing walk. Withernsea and Hornsea are traditional seaside towns, and Hull or Beverley are under an hour for shops and museums.
