I do not consider it pet intolerance, as I had to board my own pet when I stayed at Casa Ybel.
It has to do with 52 families using the same unit through the year, and also sometimes a cleaning problem.
We can't expect everybody being able to live with cats, dogs, mice, or snakes. I had all the above in my old home in Ft Myers.
I had friends that just could not visit us if pets had been in the unit one time or another.
Just like smoking, I do enjoy a small Cerut once in a while and do not feel bad smoking it in fresh air, I have been in homes that just made you sick from the smell of tobacco when visiting.

I appreciate your balanced viewpoint. While any individual may prefer to do something, there is a sense in which there must be a boundary when it adversely affects someone else.
