These 12 eccentric hotels highlighted by TripAdvisor provide an unforgettable sleep.
Innel Hotel Zaandam (Amsterdam)
At first glance, this hotel appears to be made up of a series of houses stacked one on top of another.
Inspired by the architecture of traditional houses of the Zaan region, the green facade of Innel Hotel Zaandam is eye-catching even from afar.
Located next to the Zaandam train station, it takes only 12 minutes to get to the Amsterdam city center.
Faralda Crane Hotel (Amsterdam)

The Faralda Crane Hotel is located at the top of the 50-meter-high structure and there are only three suites available for booking.
If staying atop a former industrial monument isn't exciting enough, you can rope-jump off the crane and free fall 164 feet.

Famous for its donut-like shape, the Sheraton Huzhou Hot Spring Resort in China offers amenities and services that are even more attractive than its architecture.
For one, there's an underwater bridge that connects the two towers of the hotel.
At night, there's a spectacular light show during which the building's distinctive structure isilluminated.
Hotel Jested (Czech Republic)
Built in the 1960s, this hotel looks more like something from a sci-fi movie than a place to spend the night.

According to the hotel’s website, railings in the interior of the hotel are made of discarded pieces of steel that have been welded together, giving the place an industrial feel.

Want to go on a cruise but afraid of getting seasick?
South Korea’s Sun Cruise Resort may be your answer.
Calling itself the “first luxury cruise ship on land,” the resort offers everything you'd experience on a luxury cruise ship -- except maybe seasickness.
There's even a rotating sky lounge offering great views of the ocean.
Spitbank Fort (Portsmouth, England)
Spitbank Fort sits right in the middle of the sea.
With a distinctive circular concrete exterior, the English site has been transformed from a gun emplacement into a luxurious private island fitted with a rooftop pool, sauna and fire pit.
Oh, and there's one small thing that might add to the unique experience -- an alleged ghost resides at Spitbank Fort.

The cars in the train sit permanently on 700 feet of railroad track that overlooks the Tanana River, mountains of the Alaskan Range and city of Fairbanks.

La Balade des Gnomes (Durbuy, Belgium)
La Balade des Gnomes looks like an odd farmhouse, but it's actually an imaginative hotel with 10 guest rooms.
From the Trojan horse suite to the "sailboat" in its own pool, each room's design is inspired by a fairy tale.
Hotel Costa Verde (Costa Rica)
This vintage 1965 Boeing 727 airframe is located in the jungle canopy of Costa Rica.
