Its not a bad spot. I personally think staying at chain hotels in the Northwoods is gross but there is a Days INN right on the "trail" that ATV'ers and snowmobilers stay at. Walk to Trackside, Bars, Restaurants, Downtown Eagle River not far either.
Pricing is very reasonable at Trackside compared with renting Polaris in Ironwood.

The same owners of Trackside have a dealer in Watersmeet if you want to drive even further or find availability issues also...
I would just call them soon. Last time I tried to rent something "late" in the season they had already needed to return the rentals to Polaris. They do some rental program with them and do not own the ATV's themselves. Not a bad deal cuz they are current and not very beat up.
