We had a 27kw gen in our large home in VA to power the Airco. We put it in after the 2012 Derecho from Hell left us without power for 5 days in 100+ temperatures and ruined 3 refrigerators full of food. It was a miserable experience, but at least we could go to work and have light and most important - Airco. Up here on the island we just installed a 14K Kohler for a much smaller place. The unit was $4k, the installation was about $5K, which included delivery on a front end loader from the dock, gravel bed and tying the genny into the propane tank. work was just finished last Saturday. I am part of the island's wellness/aging in place team and see the value as a cranky retired sort of being able to shelter in place. Losing some food was small, but very irritating issue. The bigger issue for us, especially in the last power outage during the October Noreaster ,was we only have about 9 hours a day of usable sunlight a day during that time of year. Sitting in 15 hours of darkness drove us crazy, hence the generator. Understand the nice hotel gig, but I think it probably works better on the mainland.
