The best course of action is to develop a relationship over time. Consider this: in many parts of the world - today - many marriages are arranged by the 2 families. Sometimes, the bride and groom see each other for the first time the night of the wedding after it's all said and done. Do these marriages fail more often than marriages based on a long courtship period and co-habitation first? I doubt there are reliable statistics for that. But the way I see it, if the couple is young (or flexible), and not already set in their own rigid ways, they'll adjust to each other and change.
