My one burning question right now is will Ikon still have those resorts on the pass? Is there anyway to find out what resorts will be on the pass for next year?
To answer your question, no, I'm not aware of any way to find out exactly which resorts will be on the pass next year.
That said, I wouldn't worry about it, TBH, and I'd be shocked if those resorts aren't on the Ikon pass next here. Here's why...
The company that owns the Ikon pass (Alterra) owns Solitude. So at the very least, you're guaranteed Solitude will be on the pass.
Brighton always seems to go wherever Solitude goes, since there's too much to be gained from their interconnection. So if Solitude is guaranteed Ikon, Brighton should be too.
As far as Alta/Bird, I suppose it's possible they could leave. I seriously doubt that though. Those two mountains are arguably Ikon's biggest draw. Since Ikon relies so heavily on them to help sell Ikon passes and compete with Epic, I think Ikon would do whatever they could to preserve that relationship. I also haven't heard the Ikon backlash from those resorts that you've heard elsewhere, so it's not like tensions are bubbling over or anything. I suppose some locals would know this better than me though.
Plus, you could always: a) Ski Deer Valley, which is also owned by Altera and would only be 15 minutes further from your Sandy house than Solitude/Brighton is. b) Get a Ski City Super pass which is $1,000 for 10 days at Alta/Snowbird/Brighton/Solitude c) Get an unlimited pass to Alta for $1,000 or $750 for midweek d) unlimited pass to Snowbird for $1,200 e) Mountain Collective pass f) etc. g) etc.
All that said, Ikon began selling this year's pass on March 5 last year. So if you're really worried about it, you could just wait 1-2 weeks to book your place.
