We’ve stayed at the Bay Inn many years and it was great for fishing trips. Nothing fancy but safe, secure, restaurant onsite, good parking for truck/boat, electric plugs, free ice, and great prices. Ask for a double room for extra space. Here is a link: http://www.baymotelgreenbay.com/
You can also contact Lipskeys Hotel which is about 15 miles north east of Green Bay in Dyckesville which has reasonable prices and has a gas station across the street which is open at 5am with tackle and bait along with coffee in the morning close to boat ramps.
