Don't blame Ikon, blame the $$$
Vail and Epic Passes showed an industry that drank the real estate cooled of the early 2000s how to make money. And that answer tends to be found more in high spending destination skiers. While that crowd is not going to be novice beginners, they will be not be hard charging locals. But, if you are dropping thousands on a trip to Jackson Hole, and you can't say your skied off the Tram....its what they are selling
At JHMR you also need to follow the money--being spent.
2008 saw the needed rebuild of the Tram. Folks got a better Tram, but the same mountain, and a rebuild that was mechanically necessary.
Since 2008? Money has gone to Capser, Teton, and Sweetwater lift projects, and the new learning center. Jackson Hole has been spending close to a decade trying to change and expand its image from just dropping Corbets to a place for everyone. You don't pour millions into infrastructure for blue groomers, and families with kids unless you believe they will come and spend money.
JHMR is doing what is smart to become financially successful as an independent area. They are resting on the brand the Tram and Corbets etc has build amongst die hard skiers, and sought to expand their appeal to lower intermediates and families with younger kids. When you expand your appeal like that successfully, you are going to bring in more skiers, alienate some old customers, and drastically adjust the type of skier on the mountain.
Don't blame Ikon, blame every bit of $$$ JHMR has been spending in the past decade, and every $$$ they bring in from making awesome terrain into an appealing resort.
