Take your diving gear along to reach an underwater hotel; stay in a disused US Air Force radar tower in the heart of the equatorial rainforest; slide back the roof of your bedroom to gaze at the stars; sleep in the cabin of a dockside crane that you can rotate, or in chalets hidden in the forest, a survival pod from an oil rig platform, a giant shoe, a coffin, lighthouse, tree, plane, train, chapel, prison, igloo, or even a red cube lost in the countryside …
