Rooftop glamping has recently taken New York by storm.
This year, visitors to the Big Apple can spend the night in a bed on the roof of the AKA Central Park, and guests at Manhattan's Affinia Gardens hotel can spend the night in a tent on one of the hotel's terraces, with flashlights and a smores-making kit thrown in.
There are other weird camping experiences around the world.
Camping Vliegenbos, Amsterdam
Part campsite, part art project, the Camping Vliegenbos campsite allows visitors to spend the night inside a wooden cube, a suspended dome or a camper that folds out to become a garden -- complete with stuffed badger and artificial trees.
Located in a peaceful forest setting, the campsite is the work of Dutch artists Annette Van Driel and Francis Nijenhuis.
The campsite closes in late October.
Otro Mundo, Sierra De Segura, Spain
The cozy little domes at Otro Mundo are ideal for those who want to surround themselves with nature but don't want to spend half their vacation struggling with tent poles and guy ropes.
Located in a remote corner of rural Spain, Otro Mundo's igloo-like eco-pods, which can sleep up to five people, are fully furnished and have solar-heated showers and composting toilets.
It's a good location for hikers and mountain bikers and the entire campsite is run on solar energy.

Glass ceilings, a telescope and sky chart help guests do some stargazing.
There's also a tiny kitchenette, television and toilet.

Wilson Island, Queensland, Australia

Guests need to stock up on supplies -- the closest island is (significantly larger) Heron Island, 45 minutes away.

Red Kite Tree Tents, Powys, Wales
A different kind of tree house.
The Red Kite Tree Tents are canvas domes suspended from trees.

That makes it a good time to visit Livingstone Lodge at the Port Lympne Wild Animal Park.
This is one of the few places in the UK where you'll be awaken by a lion's roar.
