Egypt or China. Either one is nice.
I picked Egypt because idk why. I think I'm biased toward it at the moment. But it is beautiful and you could earn some decent money there. Probably could in China too but it's been a while since I've played there so IDK. China and Egypt are both gorgeous and exciting destinations. Either would be good. Others make a good point about Egypts camp though. But I guess it depends what your sims get up to. Mine are never at camp and sleep in tombs anyway.
France as much as it's the typical romance destination... the world is awfully underwhelming IMO. Egypt and China are so gorgeous and France is... ehhh. It's okay.
