Weekend near the sea with a child and a dog ideas please - Air B&B?

[ByAmberteacher]

Hi I was given Air B&B vouchers for my 50th birthday recently. I would like to go to the sea (preferably no more than 15 min walk to the sea) for a weekend away anytime from now until when the school summer holiday start.
There will be me, my daughter who is 12 (she's autistic and does not like to be in flats / apartments as she gets worried about getting out) and our dog. The dog isn't great in the car, so I think travel over 3 hours will be too much. We live in the Midlands. I seem to have been looking for ages with no joy and then realised I always come on here to find the answers to everything - so thought you might have some ideas for places to stay. THANK YOU

Dorset (Purbeck/Corfe/Swanage)? Not sure exactly where you are and whether that fits your travel time.
Or south Wales? Pembrokeshire?

Filey? Or is that too close, I love Whitby but it can be very busy and Filey is more laid back.

Gower? Just stayed in Mumbles in a dog friendly airbnb, beaches in walking distance

Somewhere on the Norfolk coast? Hunstanton? Cromer?

Parkdean have a 4* site at Skegness which is about 3 hours from you, (Southview Holiday Park). I stay at a Parkdean park on the East Yorkshire coast every year with my dog. The sites are safe, have lovely clean, modern static caravans to hire, with free WiFi, gas and electricity. They are dog friendly and there's loads of activities for kids. They're worth a look.

Plenty pet friendly houses on airbnb in Conwy area lots of lovely walks

Put filter for house and pets

Northumberland - some of the best coastline in the country and tends to be nice and quiet.

North Wales, plenty of nice beaches both busy and quiet, the Llyn Peninsular is spectacular, Area around Conwy / Llandudno is a good base.

Thank you so much for all the ideas! I am going to look at everywhere you have suggested. Thank you
