Last week I had the chance to stay overnight in the Aurora Bubble Hotel, known as the 5 Million Star Hotel, so I took my Mum and we headed off to sleep in a bubble under the stars. A beautifully crisp winters day, we arrived into a winter wonderland, ready for the Aurora and to sleep under a blanket of stars. The Bubbles act like a hotel and provide you with a room which is fully transparent, providing the perfect Northern Lights Hotel. Each Bubble sleeps two adults in a comfortable double bed, minimum age is six years old for health and safety reasons. The structure is completely inflatable and made out of a fire-retardant PVC tarpaulin, you literally sleep in a bubble. The structure keeps itself inflated by a slight over-pressure from a noiseless ventilation system. The system is designed to renew the air 2-7 times per hour, this also prevents any humidity. The system has an heating element with thermostat so the Bubble is cosy and warm all winter.
