Covering (no pun intended!) tents in this post. Not too many people (with enough moolah) actually live in tents, but quite a few vacation resorts (on beach, wildlife reserves, mountains, desert) offer accommodation in tents. Some of these are faux tents - with walls made from bricks/mud but designed and stylised like a tent. Take a look at these yum images below:

Sigh...am ready to pack my bags and live the nomadic life... well...luxurious nomadic life that is!
If this inspires you to get that tent up and running in your back yard, you can find some good options here and here too. A room (ideally a sunny room with a view) can also be styled as a tent with fabric on walls and a canopy. Use wall scones shaped as lanterns and some nice rustic furniture pieces, a planter or two, and you have a tent in a room ready!
