Yolanda's place isn't an option. When I have mentioned AirBnB places to her in the past she has been concerned about security.
What's the alternative to something like AirBnB for short term stays?
She could try to find a private rent, but is that viable for a few days at a time, and let's be honest they'll carry the same security risks, if not more, than AirBnB
Alternatively there's hotel rooms - I know she was looking at this at one point because I had a booking with her but it fell through due to issues getting from Liverpool to Northampton. We've all heard of 'Rain stops play', this was a case of 'RMT scuppered fun (short notice rail strikes)'. There's the fun and games of getting her guests past reception but beyond that I'd say they were probably the most secure option
