Sounds like a perfect plan to me!
Starting with PCMR, then The Canyons -
- Then Snowbasin, Powder Mountain -
- Then Brighton, Solitude
- Then Snowbird for the final day.
You are going from mellow to more advanced and intense terrain each resort/day, which should be awesome!
Just pray for snow, it looks like we are headed into a harsh dry-spell for the next couple weeks, but December and the middle of January have been great. Record breaking snowfall fell here in downtown Salt Lake City so that should clear up by the time you arrive (walking and driving have been awful!) but the cold has been more brutal than I can remember, SLC has been in single digits for most of January, PC has seen negative temps quite a bit too. It's currently -8°F in PC, and it reached -42°F in Northern Utah today. If this cold continues, DRESS WARM!
