Useful UK web site for accessible holiday rentals

Well at least you get room service Mike! 

There is place in Lancashire called Brickhouse Cottages where we have stayed a couple of times that would be able to accommodate your needs if you felt the urge Mike

But I know what you mean - sometimes taking a holiday is more trouble than it's worth and I guess there will be some forum users who do and probably more that don't. Peter and I try to take a short break (3 or 4 days) once or twice a year as a change of scenery and some sea air is good for both of us. And as he has some mobility it's also good to challenge himself in new surroundings (at least that's what I tell him). 
Sometimes it's fun and sometimes we wonder why we bothered. 
But I do know other w/c users who love their holidays and that's why I post new sites when I see them.
Researching is either fun if you like it (I do) or a pain in the bum if you don't.
Also I am a frustrated traveller and this way I get to indulge my imagination If anyone wants some holiday research done, I'm your woman ....

Full disclosure virginia, is that I am the frustrated traveller and Peter is a bit of a stay at home these days. He was even before his mobility became so compromised. He travelled a lot in his working days to some very exotic places and stayed in 5 star hotels. So he has "been everywhere" and stayed in the best places and no real desire to add to his experiences. Holiday plans are always initiated by me. 
I am  the frustrated traveller and my bucket list is long. Peter isn't keen to have anyone but me doing the caring role - so for the time being - my plans are on hold. 
Would you find it easy or hard to travel? Do you stay at home because of the difficulty of the travel or suitable accommodation? Or are you just happier at home?
