Unique hotel stays to try before you die

Castle Hotel Ashford Castle County Mayo, Ireland First up, Ashford Castle. Ashford Castle embodies the fantasy of the Irish castle hotel, featuring a massive historic stone facade, complete with towers and turrets; gorgeous, manicured grounds; a stunning setting on a huge lake; and common spaces that are truly grand, with rich wood paneling, chandeliers, and antique furniture. The wide range of estate activities includes falconry lessons, boat tours on the lake, golf on the 9-hole course, clay shooting, and archery. (Oyster)

Lowcountry Estate <a href="http://www.oyster.com/south-carolina/hotels/the-inn-at-palmetto-bluff/">The Inn at Palmetto Bluff</a> Bluffton, South Carolina, United States This "inn" in Carolina Lowcountry, really more akin to a sprawling estate, provides a one-of-a-kind experience that uniquely blends southern history and almost otherworldly natural beauty: rivers, misty marshes, old oaks draped with wispy Spanish moss, and salty breezes. The main hotel building looks like a classic southern mansion, and the 50 Cottages and Cottage Suites are simultaneously homey and utterly luxurious, with working fireplaces, screen porches, and gorgeous bathrooms. The multi-bedroom Village Homes are also luxurious, but lack some of the nuances of the cottages. Guests can enjoy a range of recreational facilities, including golf, bicycling, tennis, croquet, kayaking, and swimming (in the two pools), and the luxury spa is highly acclaimed. It's not an overstatement to say that the Inn at Palmetto Bluff is one of the most special properties in the entire country. (Oyster)

Bohemian Hideaway The Gallery Inn Old San Juan, San Juan, Puerto Rico Owned by the same couple for decades, the historic Gallery Inn is run like an informal B&B -- guests are greeted by name, much of what the restaurant serves is grown in the garden, and no two rooms are the same (though they do share lots of Spanish-style charm). Also like a B&B, the hotel lacks amenities such as TVs and a fitness center. The property's main draws include the convenient Old San Juan location, ocean views from the wine deck, and the artsy, laid-back feel. The innkeepers are both artists, and it's evident they put thought into every detail of the restoration -- expect beautiful old-world details like brick floors, wood beam ceilings, rich rugs, sculptures, and antique knickknacks.

French Chateau Saint James Paris 16th and 17th Arrondissements (Bois de Boulogne), Paris, France With a sweeping private entrance surrounded by green lawns and an impressive fountain, the upscale Saint James is a rare find in Paris -- in fact, the 19th century manor is considered the only chateau-hotel in the city. It's fitting that the hotel is located in the wealthy 16th arrondissement (and yes, valet parking is included). The 48 rooms and suites are large by Paris standards, and decorated in plush luxurious fabrics. But the common areas are more impressive -- especially the black and white grand staircase on the main floor. The terrace is a beautiful spot for lunch on a nice summer day. And there's also a small fitness center, a spa, and a gourmet restaurant. The rates here are steep, but guests who want to experience luxury in Paris (and can afford it) should give the Saint James a look. (Oyster)

Lofty Mountain Lodge Spring Creek Ranch Jackson, Jackson Hole, Wyoming Set in a wildlife refuge more than 700 feet above the Jackson Valley, the Spring Creek Ranch has arguably the most stunning views of the Tetons in the area. It has a wide array of room categories, from standard hotel rooms to immense two-bedroom condos, some of which are ultra-luxurious. The delicious, popular restaurant and the excellent heated outdoor pool are not to be missed. (Oyster)

Unplugged Tropical Getaway <a href="http://www.oyster.com/riviera-nayarit/hotels/haramara-retreat/">Haramara Retreat</a> Sayulita, Riviera Nayarit, Mexico Haramara is arguably one of the most special hotels in Mexico. It is a luxurious yoga retreat located on 12 seaside acres of wild vegetation just outside Sayulita. The structures have been built using traditional construction techniques to minimize the environmental impact, and there is no electricity anywhere besides the restaurant and the yoga studio -- not even in the rooms. Each room is housed in a private standalone thatched hut with no window panes or screens separating it from the jungle, and only gauze curtains and mosquito nets to avoid bugs and critters. It is geared towards those in need of some detoxification and relaxation, with yoga and meditation classes, an open-air spa, a vegetarian and seafood restaurant, unpaved trails, and limited cell phone service.

It’s located near the subway as well as dozens of restaurants, bars, and shops in the heart of trendy Williamsburg. Rooms are spacious and have high pine ceilings, reclaimed wood furnishings, and great amenities, including flat-screen TVs; local, hand-made toiletries; free Wi-Fi, and radiant floor heating. <a href="http://www.oyster.com/hotels/theme/travel-inspiration/slideshows/15-unique-hotel-stays-to-try-before-you-die/">See all 15 unique hotels here</a> (Oyster)
