While you are planning on leaving your generator at home, I suppose, remember to bring bear spray with you or be prepared to buy some when you get to the Park. And remember, you can't leave anything outside a hard-sided enclosure that smells of food, it draws bears as well. Unless, they have the bear boxes or the hangers in the trees. Not trying to scare you, just the facts of life in the Park. Bears are getting more numerous and it's not nice to have one around your food. As far as generators, Colter Bay has about 125 or so sites that are generator free if you would consider camping there and day-tripping into Yellowstone. We camp in Colter Bay, where they allow generators, and when not fishing, we generally take one or two day trips to Yellowstone. Get up early in the morning and get home late in the evening, but the trip is worth it.
