Personally, I try to stay away from RV Resorts, but google search turned up these:
No. 1 Luxury RV Park -Polson (Part of a review: "Great views of the lake and mountains out your windshield. The pool is small and the hot tub adequate and it is shared with the KOA. However, there is a nice but small fitness center for the resort. I stayed 7 days and loved the experience of the resort and Flathead lake." Ditto on a 2nd review: "Escort to the site. Check in after you are settled. Manager greets you at your site with gift bag. Daily news paper delivered to your coach. Trash pick up 2 times per day. Wine and cheese mixer on Friday. Breakfast on Saturday. Shuttle to farmers market. Great views. Attention to detail. Clean with lots of space.")
Eagle Nest RV Resort -Polson (Part of a review: "Paved roads, level gravel sites, many trees, wonderful people in the office, owner who takes a "hands-on" approach to making sure everything is done correctly, pool (didn't use, not open yet), hot tub that was, very clean restrooms and showers. It was quiet as it has one of the most attractive Mobile Home Parks I have ever seen in front, a golf course in the back and not much on either side. Birds are the only thing that will wake you up in the morning." Another review: ""Resort" is right. Very clean, pool was great. Close to bike and hiking trail around the city of Polson. Close to Flathead lake and town. Staff very friendly. They even have a "cocktail hour" with appetizers by the pool at 4:30 every day. Really enjoyed our stay there and would definitely stay there again. The sites were level and very well maintained. Sites weren't real spacious but adequate.")
MT Guide: RV Park, Campgrounds & ResortsWest Yellowstone:
Grizzly RV Park and
Yellowstone Holiday RV Park & MarinaWith a week to 10 days, a detour over to Teddy Roosevelt Nat'l Park might be neat (a cool area) by
Medora, North Dakota.
Not a true resort, but
In A Pinch ?; sadly no hot tubs.
