Holiday advice

Hi, Can anyone give me some advice about dialysis holidays in the UK please. Dad seems to think that he's seen adverts for hotels that actually have hemodialysis beds - but now he can't find where he saw it! He and Mum are both late 70s and want a short break where he can get his dialysis easily. Any ideas? I know they can get a hotel near to a hospital with a spare bed but most hospitals are in towns and they would really like to go to the coast! I have found a list of hospitals but without trawling through and looking each one up (which I will if I have to) I can't tell what sort of area they are in. It seems like a holiday in Crete or a cruise would be easier to organise, but they only want a long weekend!!

All information and ideas welcome. Thanks everyone.
