It's very pricey in Jackson, hell the people who work there live in Driggs, Over the Teton Pass which is a heck of a commute (10% grade for 7 miles - both sides).
And this would be the . worst. year to visit either Park. There were 3.4 million people who visited YNP in 2014; 4.2 million in 2015... and it was traffic gridlock for the majority of the day, every day from 4/26 when the roads opened until 11/2 when they closed. It was insane, people were rude, pushy, drove like idiots... at least one head on crash each week... People crowding around the animals and doing everything they thouight they could get away with because "rules suck" and shouldn't apply to them. And then there will be an additional 600,00 Chinese folks showing up, most on buses with kamikaze drivers bu worse are the many thousand who show up in a car they have to idea how to operate, no clue about driving rules or courtesy, and they have no licenses either (got one online type so they could rent the car). So there's that. The parks are understaffed and there won't be an LEO when you need one due to the shortage. And then there's the 4th grader program to bring in untold thousands more and the centennial to boot. I live within a stone's throw of the park and I will not go in the park at all this year, in fact, I have taken a job 60 miles away just to be away from the traffic and tourists.
Too many people in a sensitive ecosystem will surely be the death of it.

FYI.
Sorry for the rant but I spent the last two summers working as a Ranger in YNP and I never want to be exposed to the GP like that ever again. I was held to an impossibly high standard last year given the number of people we saw last summer. I know for a fact, because we actually keep count, that I spoke to at least 1200 - 1500 MORE/week people last summer than I did in 2014. I worked hard in college to study this place so I would be able to come work here only to be chased off from one of the least populated places due to overpopulation for 6 months of the year. After 11 years, I and many of the long-time locals, are looking to get the hell out of here. Most of the real estate in the area is being scooped up, cash in fist, by Chinese investors too so it won't be long before Yellowstone is surrounded by corporate interests and nothing more.
