"Glamorous camping": tent, butler, $595 a night

The number of visits to U.S. national parks is declining, but "glamping" — glamorous camping — is on the rise in North America after gaining popularity in Africa and England, where luxury tents come with Persian rugs and electricity to power blow dryers. Resorts such as Paws Up that expand on the dude-ranch concept are reporting increased bookings, another sign that luxury travel remains one of the strongest and fastest-growing segments of the tourism industry.
