There are 2 ways to get in there off of 3. You can come in the feeder trail that is access for Americinn. (This is groomed half way in to just behind Houghton power sports, groomer barn) Go up the road towards Walmart, cross the road at the light. And run the sidewalk 1 block to the motel.
Or run trail 3 further north till just before the road crossing at the bridge. Take the trail off to the right that goes up the hill. That will put you on a street behind the Econfoods store. Following the street towards the grocery store, cut through their lot by the gas station. Cross the side street into Holiday Inn lot. Normally enough snowmobile tracks to guide you in. If any warm weather before your visit you may encounter some bare pavement either way. When I was up that way last week roads were hard pack no pavement showing. But city was starting to scrape roads trying to get them bare.
