From time to time, London’s Hoxton Hotel offers rooms for just £1, so long as a guest can get a little lucky while making a reservation. The next sale starts Thursday, May 13 at 12 p.m. London time (7 a.m. EST). At that time, 500 rooms will be offered for £1 per night for reservations between May 14 and August 31, 2010, and another 500 rooms will be offered for £29 (about $43). As you’d imagine, rooms book up quickly at these rates. More details here.
