Well, I like Andorra for a girl much better than I like
London or
Paris. It actually sounds feminine, for once! If it's in honour of the place, I'd strongly recommend spelling it Andorra.
Andora, in Greek, could mean "man's gift" (from
aner "man" (genitive
andros "of a man") and
doron "gift"). It's kind of a nice meaning, I think, and the name itself is also very pretty.
So, in summary, I like both Andora and Andorra. But I wouldn't consider them to be the same name.
