Oh, @Blossom1961, you are having a lousy time on all fronts. The best news is positive - hubby is getting away from that awful boss and you won't be hearing him being attacked all the time. That is more stress and certainly not helpful cancer-wise.
The house sitting idea is a good one if your dates coincide. I have known people do that when others are heading overseas so that may be a chance.
Do you have any mates in the caravan park industry who can offer you a cheaper rate for a longer term occupancy ? Also, accommodation places which are rented out to holidaymakers may be an option - we have found they do a decent rate for longer term rentals - and the offer of cash is always a bonus to people !
Thinking of you. 💖
