If your travelling companions are all male I would suggest Ukraine or Poland as "other than the norm" destinations. Both feature a superb selection of those from the female gender, and it will cost you pennies to wine, dine and feast yourselves on great food and whatever else may take your fancy.
Alternatively, I would suggest Siena in Italy. There is a small airport just out of town not often used by IFR traffic. It is in the heart of Tuscany, and is without doubt one of the most beautiful cities you will visit. The airport is named (don't trust the spelling) Campiguagino, but Florence is not too distant as alternative when visiting Siena.
