ExDancer - you seem keen to remain polite whilst refusing and I understand completely. However, if you give the impression that your refusal is a 'one off' because you have plans for something else at that particular time, or you just want a rest for this year, you won't solve the problem and you need to be honest as others have said. Don 't beat about the bush. You've no longer got the energy to host and it's more important for you to have privacy in your own home. So, suggest some local accommodation, and then upscale if you feel you want to by offering a lunch or dinner, but downscale by suggesting you meet in a restaurant or for a picnic. There's nothing wrong with saying "sorry but it's no longer convenient". I had this problem when I lived in London and had two small rooms with decent sofabeds that were used as sitting rooms/workspaces during the day. One particular relative often came "for work" turning up in time for dinner, and leaving the following morning after breakfast. I knew that the employer gave a generous overnight allowance but that was simply pocketed without even a cheap bottle of wine, bunch of flowers, or box of chocolates being brought. On one occasion I learned after the event that there was no "work" commitment and we were simply a convenience while they visited an old friend. Whether it's for one night or three, you're still left with a room out of action and the bed linen to wash and bathroom to clean. The next time we were 'told' they were coming, I simply said it wasn't convenient. You really do need to be straightforward on this otherwise your summer 2026 will disappear.
