You can go the cosmopolitan route--which many published settings (by the book) aren't.
You can go the "adventurer underground" ("water margin") route.
Even those make it hard for me to rationalize the party of 3 elves, 2 half-elves, & one human beginning their adventuring careers in a human-dominated kingdom. It becomes even harder the fourth or fifth time.
But I also hate the disappointment when you tell them there's no elves in this setting.
