Update (Nov. 17): March 10 and 17 are no longer available.

Imagine yourself as royalty at an Irish castle voted the No. 1 Resort in Ireland by Conde Nast Traveler's Readers' Choice Awards 2012.

The Ashford Castle, which can command more than $300 per night in winter, offers Travelzoo subscribers a nightly rate of $159 (€125) for travel through March. This deal includes daily breakfast for two adults and all taxes.

This caliber of savings is rare at Ashford Castle, a fairytale destination that has Frommer's saying: "Bedrooms convey an air of privilege with heavy fabrics, soft carpets, and big, comfortable beds." In summer, expect to pay $500 to sleep here.

Take advantage of this exclusive deal over the following dates, including Valentine's Day and St. Patrick's Day:

• Nov. 14-15, 18-22, 25-29
• Dec. 3-6, 8-14, 16-23
• Jan. 2-3, 16-17, 20-23, 27-31
• Sunday-Thursday nights in February-March

Originally built in the 13th century, Ashford Castle has wowed high-profile guests such as former President Ronald Reagan, John Travolta, Brad Pitt and Pierce Brosnan -- who got married here.
