Thinking about this again.
Toward the back end of last year, I had a job to do in Scotland, then the last two days of the week I was on a course in London.
Now, the course & accomodation I was paying out of my own pocket.
The travel from home to Scotland, to London to home, was covered by the job I was doing, negotiated.
Now, to save money on acomoodation, I stayed with my cousin in London, only the second time ever, she's lived there for over 30 years, the first was to see Queen @ Wembley in 86, when 4 of us went.
Now I had my own room, adjacent shared bathroom, there were another two in the house, keys, wifi password & free run of the kitchen. I was staying with family, who I have been really close with over the years, even though seperated by distance for some time.
I felt REALLY uncomfortable, I was made more than welcome, but, it didn't stop me from feeling awkward.
I prefered my own space in the Holiday Inn in Edinburgh, even though it was not as convenient, or as homely, it was just what I was used to when travelling on business.
Would I stay with her again, possibly, because it worked, and I'm thinking that the scond time, might be easier, and digs in London are stupidly expensive! So only if I was paying myself. If I was on business and clients were covering the costs, then I would choose a hotel.
So, just to put a personal take on things, offering a real life comparison.
