Part installation, part hotel, artist Carsten Höller's Revolving Hotel Room is New York's latest impossible-to-get reservation. Revolving Hotel Room is part of the Guggenheim Museum's theanyspacewhatever exhibit, a group of installations by 10 artists who commonly express exhibition space as an important medium.

During the day, visitors to the museum can inspect the four rotating discs upon which Höller has assembled areas to sleep, work and eat.

By night, guests willing to pay the $799 per night rate can sleep over (no word on whether the discs keep rotating while you sleep). Here's hoping the museum extends the exhibit past its January 6 end date -- every night up until then is already sold out.
