We (my husband and myself) had already given up holidays prior to Covid19, due to disability. Yes, I do know that there are (expensive) holidays that cater for people with disabilities. My husband's problem is a back injury, which also affects his right leg, and he cannot manage steps. He is quite tall and struggles to bend, as well as sitting down or getting up again. he needs extra tall furniture and sanitary fittings, so that he doesn't have to bend too far down, and can get up without additional pain (he has constant pain, both night and day). Rooms for disabled people tend to be built for those who are wheelchair users, which he is not. He won't consider one, despite not being able to walk far. His problems also mean that we cannot go to cinemas or theatres, or most places of entertainment. Having tried for several years to find suitable self catering properties, we gave up! We are now planning to move to the North of Scotland, close to the sea. He has bought himself a camera carrying drone, and I bought him a powerful telescope, so that he will be able to see the wildlife he loves, but cannot otherwise get to see.
So........... no holidays for us, whether Covid is around or not!
