Hotels are usually just a place to crash on a vacation, but sometimes they can be the attraction themselves.
From ice manors in Sweden to al fresco wooden lodges in Botswana to hanging pods in Peru, some hotels can make your trip unforgettable.
Here are the ones you need to visit during your lifetime.
Little Mombo Camp in Okavango Delta, Botswana.
Guests can watch lions and zebras pass while they eat breakfast at this hotel in Botswana, a landlocked country in southern Africa.
Located in the Moremi Game Reserve, it offers outdoor pools and luxury tents with windows to watch the wildlife. It also has a conservation center where guests can learn about the animals.
Cost per night: $1,750 per person.
Treehotel in Harrads, Sweden.
This adult tree house will make you feel like a kid again, nestled in the trees of a forest in Harrads, a village in Northern Sweden.
Six "treerooms" and a sauna hovers in the branches 13 to 20 feet off the ground. They're all different shapes, from a UFO room that looks like an alien pod to a Mirrorcube with mirrors that reflect the forest and Lule River Valley.
The treehotel is also environmentally friendly. Every cabin has hydroelectric heating and an electric-powered toilet that destroys waste at 1,110 degrees Fahrenheit.
The pods are snug at 258 square feet, which is a little smaller than the average one-car garage. But that's obviously part of fun.
Cost per night: $505
Skylodge in the Peruvian Andes.
If you don't have a fear of heights, you should stay in this transparent pod, one of three suspended on the side of an Andean cliff.
To get to a pod, you need to hike up part of the cliff and then zip-line 1,000 feet over. Each of the "rooms" has four beds, a bathroom, and a small dining area that sits above it.
The reward for conquering a fear of heights: stunning views of Peru's Sacred Valley.
Cost per night: $300 per person.
