Holiday in UK with disabled child - ideas please

[Godesstobe]

I'm looking for ideas on where to go in the UK in June 2025 for a family holiday with 5 adults (4 in their 30s and a 70 year old grandma) and two babies (a physically disabled 2 year old and a 6 month old baby). The 2 year old cannot walk and will be in her specialist pushchair. She may also have a hand controlled Whizzi Bug wheelchair by next June.
We know Cornwall well as we have relatives there but we thought it would be nice to explore somewhere new. We are thinking of the Isle of Wight or Devon. We don't know either. Other ideas are very welcome.
We thought it would be nice to be by the sea but we would like something to do/see as well as a beach, especially if the weather is awful. We think self catering would be easiest with two babies. An indoor pool might be an alternative to a beach.
We have considered but rejected the Channel Islands as the 2 year old needs to be within no more than two hours of a decent hospital if she becomes unwell.
Any thoughts please?

I can’t recommend anywhere to stay but we took our GD to the Isle of Wight this summer and there is loads to do for children and lovely beaches.

I should add that we are all based in the south of England.

If you’re willing to travel North, Northumberland is stunning I’d say Almouth, Alnwick Bamburgh or seahouses. You would be just over an hour from the RVI in Newcastle from bamburgh and under an hour if you chose Alnmouth.

Paignton springs to mind as somewhere very wheelchair friendly. It was a few years ago that we went (pre covid) but there was an ability swing at the zoo and another in the excellent playground on the seafront. Much of the seafront is flat and level and there are several attractions with wheelchair ramps.

North Wales has plenty to see and do. Alder Hey specialist Children's hospital is 1-2 hours away in Liverpool.
Liverpool is a great destination in its self.
Plenty of good quality holiday parks, loads to see and do.

One of our Favourite walks is Aber Falls, its spectacular but they have altered the path and Wheel Chair and mobility scooter users can now access it.
Its a great 1/2 day out with a few local beaches too

Thanks @Funf . We have holidayed in south Wales before but north Wales would somewhere new. Paignton also sounds like a possibility @Forgottenmyphone . Northumberland is stunning @IggyAce but probably too far for us to drive with two such young child on this occasion.
I am grateful for all the suggestions.

have a look at Brickhouse farm cottages at poulton-le-fylde . Not cheap but excellent adapted cottages set around a fishing lake. Hydrotherapy swimming pool wirh hoisting , sensory room and nice restaurant. Lots to do in the local area and fully adapted throughout with specialist beds , wet room and hoisting etc .

Also Holistic thinking holidays have adapted caravans in various destinations around the country. They have hoists and wet rooms and some have beach wheelchairs. They are v reasonable as well. We are going the first week of Sept next year and it is only costing about 600 pounds.

Dorset is lovely and has excellent wheel-friendly beaches, most notably Studland Bay.

There is the Donkey Sanctuary and Monkey World to visit too as well as seaside towns like Lyme Regis, Swanage etc

Good to know about places with adapted facilities @flapjackfairy. The 2 year old will still be light enough to be carried and lifted next summer but will definitely needs hoists, etc when she is older. The places you suggest sound excellent.
Dorset and the Lyme Regis area is a good idea @TwigTheWonderKid. I used to go there as a child but have not been back for a while.

Isle of Wight nice but ferry essential. Rent a house. Robin Hill and Dino Park, zoos, lots of other things.
