Seaside Dreams is on South Shore Holiday Park, just outside Bridlington. It's a detached bungalow, so everything's on one level. You can be on the beach in a couple of minutes through the park gate.
It sleeps four. Two double bedrooms, one bathroom with a shower. The kitchen's fine, you've got a dishwasher and a washing machine. There's a patio out the front, it's enclosed.
The park itself has a kids' play area. The land train into Bridlington stops nearby if you don't want to walk, which takes about 20 minutes.
Bridlington's got the usual seaside things. The RSPB site at Bempton Cliffs is a short drive north. For a longer trip, the North York Moors and Whitby are under an hour's drive. York is about the same.
The place is dog friendly. You can bring two. Bedding and towels are included. There's parking right outside.
