Hotels near south end of Champlain

I’m looking for a hotel near the south end of Champlain that will allow running cords to plug in overnight. We usually stay at the Hampton Inn in Rutland Vermont and then drive to the South Bay ramp and launch. For some reason this time they are saying they can’t guarantee us power. He said there’s a 95% chance that it won’t be an issue but that doesn’t help us because once we get there if we don’t have power the trip is kind of useless. We need to park 3 trucks and 3 boats.
