The world is full of wonders, but did you know it's also full of crazy hotel rooms? These accommodations are as wacky as they are extraordinary, and they'll probably leave you contemplating a few unexpected additions to your bucket list.
At Hotel Kakslauttanen Igloo Village in Finnish Lapland, for example, you can watch the Northern Lights through the roof of your very own glass igloo.
The hotel even offers a sort of fusion accommodation, called a "kelo-glass igloo," for those who want to combine the jaw-dropping views of the glass igloos with the coziness of a log cabin and the warmth of a fireplace.
The Mitsui Garden Hotel Yotsuya in Toykyo's Shinjuku Ward offers a unique brand of accommodations exclusively for women: crying rooms.

If movies aren't your thing, a selection of tragic comic books is also available.

There are also 26 chainsaw-carved dogs decorating the floors and headboards of its bedrooms. So, no more Snoopy sleeping on top of the house. Here, Snoopy is the house.
You can even channel your canine side by going outside to go to the bathroom. See that red fire hydrant? There's a porta-potty in there.

In the underwater room at the Manta Resort in Pemba Island, Tanzania, you can sleep with the fishes... in a good way.
They offer private floating accommodations, where the bedrooms are 13 feet below the surface. It is quite literally like vacationing inside an aquarium, where you are the attraction. The $1500 a night it costs to stay in one of these underwater rooms buys you an unrivaled feeling of both serenity and oneness with the tropical marine environmental. It also buys you the ability to sunbathe and stargaze on the roof of your room, as well as dine on its private water deck.

This private wood-paneled suite has two air-conditioned bedrooms, a wing deck and views of the ocean, rendering it a rather extraordinary place to spend a vacation.
