Here is a suggestion -- just for one night, try to do without the generator. The silence is golden. For your coffee, check out the idea of "pour-over" coffee using boiled water -- it is all the rage these days, and it is delicious, and it uses no electricity. And is it absolutely necessary to use a blow dryer? In dry climates, hair will dry pretty quickly without electricity. (In a wet climate, there may be no other option.)
I understand if you and your wife choose to use electric power so that you need a generator. That is your choice. But a lot of folks camp "off the grid" and enjoy the peace and quiet. It is a lot easier than you'd think.
Thank goodness it is a free country, and you can do what you please!!
