Happy St. Paddy’s Hangover Day! If you aren’t sufficiently sauced and leprechauned out from yesterday, Travelzoo has a deal this week that might just do the trick. Snag a six-night vacation in the five-star Adare Manor Resort near Shannon for $899 this summer, including flights and car rental (flights leave from New York, with taxes and fees an estimated $127 to $137 per person). The hotel is a Condé Nast Traveler 2011 Gold List property, with an 18-hole golf course, horseback riding, fishing, a spa, and, naturally, Guinness. And summer is about the only season in Ireland in which there’s at least a 50 percent chance it won’t rain.
