Whether it's balanced on the rim of a volcano or made of crystallized salt, the right hotel can provide you with a good year's worth of bragging material. These are the kinds of places you have to go at least once, if only to say you have.
The best part is you don't need to raid the kids' college fund to find some exotic, out-there rooms.
Find a little balance in this precariously perched hotel. It was built by Living Architecture, the brainchild of Swiss philosophical writer Alain de Botton who wrote "The Architecture of Happiness."
The group created a series of homes in the United Kingdom based on high-quality, modern architecture and de Botton's work on the connection between environment, architecture and happiness.
The Balancing Barn in Suffolk, on the edge of a nature reserve, sleeps eight people. Clad in silver tiles and with large windows giving great views, it has also won a series of travel and design awards.
Living Architecture has also just launched its sixth property: a boat-shaped room where you can spend the night, perched on top of the Queen Elizabeth Hall on London's South Bank.
Cost: From US$38 per person, based on eight-person occupancy.
With views of the peaceful Yulong River near Yangshuo in Guanxi province, the Mountain Retreat Inn has been named a top hotel by TripAdvisor and The Telegraph.
It's all very eco friendly, with sustainable local bamboo used for furnishings where possible, but it's the mountain scenery that makes this one for the scrapbook. The dramatic karst peaks along the nearby Li River are a big tourist draw, while the hotel itself has comfortable, simple rooms.
Cost: A single room from US$62. tel: +86 773 8777 091
It's the surroundings here that are the attraction rather than the hotel -- but you can't trek through the forests of eastern Finland's Karelia region, over spongy carpets of moss and blueberries and under birch and pine canopies, without feeling as if you're walking through a fairy tale.
The Wild Brown Bear Hotel is a great base for getting close to Finland's natural side, and from here you can arrange an overnight stay in a hide looking out for wild brown bears and wolverines (a photographer's hide is also available).
Other activities in the area include kayaking around peaceful lakes, cycling and enjoying the great Finnish outdoors.
Cost: A one-night stay in the bear-watching hide starts from US$213 per person.

If you're in Cuba chances are you will pass through Havana, and there is no cooler place to stay than the Hotel Saratoga.
Its rooftop pool has some of the best views in town and goes some way to offsetting the traffic noise and hustle of the Paseo del Prado. It features on the Guardian's list of top 10 hotels in Havana and is considered one of the better bolt-holes in town. But avoid the food if you can.
Cost: Deluxe patio rooms start from US$238.

The Adrère Amellal eco lodge lives in harmony with its fragile Saharan environment and allows its guests to experience the freedom and beauty of the unspoilt desert too.
With no electricity, no Internet and no phone signal, you'll soon be appreciating the sunrise over the sand dunes, discovering the ancient Siwa way of life and learning how local artisans and herders are surviving in this parched landscape.
It's all built using traditional techniques -- part rock-hewn and part kershef (mud and rock salt) -- and the lodge's restaurant serves quality local vegetarian and meat dishes. Don't forget to dip your toes in the Roman springs. The lodge is a 10-hour drive (about 750 kilometers) from Cairo, it's not easy to get to, but is well worth it.

If you can't stand bland, try the Palacio de Sal, with walls, floors, beds and chairs made entirely of white rock salt.
Set on the eastern shore of the Great Salar de Uyuni, a vast expanse of white salt 3,650 meters above sea level, it's also great for stargazing at night and watching sunset colors reflect off the salt lake.
You can try your hand at a bit of trick photography -- like this intrepid traveler who appears to be relieving himself of his travel companions.
The hotel also has a spa and salty golf course. Not recommended for slugs.
Cost: Rooms start at US$100 for a single.
