Sweden’s first floating hotel, the Salt & Sill, can expand its bragging rights to include the world’s fastest floating sauna. The nautical hotbox, which opened in 2008, topped out at 18 mph during a boat racing competition in Marstrand. It has two stories and comes complete with a balcony for diving and an upstairs lounge. Each hotel room stands alone and all have private entrances. The speedy sauna can also be used as a conference room, exhibition venue, or wedding suite. The hotel floats off from Klädesholmen in southwestern Sweden. Contact the hotel for details on how to reserve.
