There’s just a lack of shared values, that’s not a criticism of them but does mean it’s somewhere I would avoid visiting.
I don’t have much time for religion so would choose not to visit countries where it is still a big feature of daily life.
We were joined by some gay friends on our last holiday and I don’t think they would be welcome.
It’s a bit too hot for me.
I find other countries culture and history more interesting so would rather visit those places.
I love a drink when I’m away and would prefer not to be confined to certain areas, if possible.
I prefer my Mrs to be free to wear what she wants.
That’s a few reasons off the top of my head.
