Holiday destinations

Can any one help .Is there any "resort" location in Mid/north England /south Scotland which caters for individual with walking difficulties requiring a wheelchair --not just hotel but places to go locally ?
I don't have any personal experience here but a swift Google search of 'Accessible Holidays' showed a few interesting looking websites including this one

and there is a holiday guide from Disability Rights UK (formerly Radar) which isn't free but comes from a well respected organisation

I hope that helps

thanks EF
