We generally do 1 trip a year where we base out of Chamberlain but hunt about a 50-100 mile radius of Chamberlain, mix of private and public. Allen's Hillside is definitely where I'd recommend. We have stayed there many times and they cater to the outdoors - hunting & fishing groups. You don't have to use their guide service to stay at the motel. It is a motel, you get what you pay for - which is plenty of amenities for a guys hunting trip. 2-3 beds per room, hot and cold water, shower, sink, toilet, TV, dog friendly, parking right outside your door, bird/fish cleaning shack. Head to the lobby for some morning and evening BS with the other hunters. Friendly place.
