Transient, or pop-up, hotels offer affordable rooms in prime spots or posh lodging near seasonal events such as music festivals.

These days, it’s hotels that are on the move, not the guests. Transient, or pop-up, hotels offer affordable rooms in prime spots or posh lodging near seasonal events such as music festivals. Sleeping Around, a Belgian company, transforms 20-foot shipping containers into luxury rooms and transports them to cities around the continent. The Pop-Up Hotel, a British firm, will supply luxury safari tents at June’s Glastonbury Music Festival, as well as a full restaurant and “exclusive luxury toilets,” no doubt a valuable festival perk. Podpads will also offer rooms at Glastonbury, but theirs look like small plywood cottages. Another business using shipping containers as rooms, Snoozebox, operated at the London Olympics, achieving 85 percent occupancy, and became a surprise financial success. This week The New York Times spotlights a few additional options.

With travelers increasingly interested in one-of-a-kind adventures, these hotels help provide an experience that few friends will be able to replicate.
