If you want to treat your sweetheart like royalty this Valentine's Day, Oheka Castle has something for every budget.

Oheka Castle is opening its doors for romantic retreats and grand tours, as well as decadent meals that won't break the bank. Each guided tour comes with a special treat at the end, including tea and cookies or champagne and strawberries. The castle also offers price-fixe lunches and dinners that overlook the grand formal gardens.

"Oheka is a great place to spend Valentine's Day," says Nancy Melius, of Oheka Castle. "Because of the beauty, the European ambience, the magnificence of the estate ... and, of course, our service and our food. It's just magnificent."

If you really want to splurge, you can take advantage of the overnight specials, which include room accommodations, a four-course dinner and breakfast the next day.
