Don't want to rain on your Columbus day weekend but call ahead 1st. CH starts shutting down after Labor Day. My wife & I went to CH may have been Columbus day weekend & most everything food, hotel,stores & sites were shut down or wrapping up that weekend which put crowds in places that were open so we waited a lot for everything not many employees available. We took pictures of the lighthouse from the bay hiked along the shoreline & hiked every waterfall in the area which are well marked did Brockway & had time on our hands. There is also a ship museum pictures of many wrecks & stuff from wrecks that I liked. 1 day is plenty of time but like I said call ahead & check. A lot slower driving a car to CH & Brockway than by sled. lol
