I'm in Whitefish right now. Can confirm this is a bad charging situation up here for this summer. I'm guessing it would probably be okay in other seasons with fewer EVs in the area. But man, they really better have a supercharger up and running before Memorial Day or it's going to get ugly!
I drove in from Seattle yesterday knowing that I'd have to find some L2 charging just to make it back to Superior or Missoula, but the situation became more urgent when I was informed that I'd be driving a group to a hike 50 miles away (100 miles round trip). This is a meetup of about 30 people, half of which are hiking. Most flew in and rental cars are a joke right now so I think we have 2 ICE rentals and 2 Teslas among the entire group (a friend drove his Model 3 up from Colorado). Kind of hilarious that half our cars are EVs in this area but it is what it is! No surprise that it was the Tesla guys that chose to road trip instead of flying in
Anyways, after looking at Plugshare, the main option appeared to be the public parking garage behind City Hall. There are 4 ~7kW Clipper Creeks total, 2 on the roof, and 2 on one of the middle levels. Unfortunately they are in a leased parking area so they are only open to the public from 6pm-6am. My Model 3 friend arrived during the day and was informed by a bystander that he would be ticketed $50 and/or towed if he left his car there. He was desperate for a few miles to pick up a friend at the airport so he plugged in for a few minutes and stayed with the car.
I arrived at 7pm and all 4 were occupied! Fortunately one was my friend who had come back and plugged in after 6pm. We coordinated and he let me know when he was going to unplug so I met him there. By the time I met him, one of the other cars had unplugged so he stayed plugged in and I plugged into the empty stall. We both charged all night and unplugged around 5am lol. Not an ideal first night of sleep, but we're up to 90% and ready to chauffer the hiking trip! In total I saw 6 EVs plugged into these 4 spots on this Monday night/Tuesday morning. 4 were Teslas (2 were my friend and I) and then there was a Bolt and a Leaf or something.
The only other options for Whitefish on Plugshare are a couple regular outlets (fairly worthless unless you are staying at those hotels), a B&B, the hospital, and the Lodge at Whitefish Lake. It was my friend's first Tesla road trip so he tried all the L2 options. He was rebuffed by the B&B who apparently have a strict policy of "guests only." He was able to charge at the hospital, which would probably work in a pinch, but seriously, who wants to hang out at a hospital L2 charging? Doesn't seem like there is much to do within walking distance of there. He was also able to charge at the Lodge at Whitefish Lake, which is probably the best option after City Hall. I believe valet controls the spots though and you are supposed to be a paying customer, so some people won't like that (they do have a bar/restaurant at least).
A cursory look at Kalispell on Plugshare is not good either. The Red Lion charging non-guests $40 for 4 hours is fairly outrageous and other than them, there are only 2 L2 plugs in town.
Bottom line is... pack your patience if you plan on coming to this area with an EV this summer!
