Some 12,500 tons of snow and ice make a mighty mess come spring thaw. But until April 3, the frozen mass forms Quebec City’s Ice Hotel, now reconstituted for its fifth season. The marvel of opaque snow-packed walls, clear ice columns, and frosty vaulted ceilings has drawn 220,000 spectators by day, 10,500 brave hearts overnight. The latter bed down inside superthermal mummy bags in 32 ice blocks — er, rooms. Warm up at the hotel bar with fiery vodka dispensed in ice-block glasses. Ch-ch-ch-cheers! $324 for two, including meals. (877) 505-0423,
