I have absolutely no objection to real-world locations, provided the names date back to the period we are mimicking.
I find region names like Faithhill, Kid's Rock, and Dantooine childish, and think that whoever suggested them as possibilities for Dwilight should be ashamed of himself.
Faithhill is just annoying to spell. I don't like the 2 H's.
Kid's Rock... I'm okay with. It sounds like it could be a plausible name. And the surrounding regions seem similarly themed.
Dantooine has always bothered me.
