I'm a former PSIA level 3 cert and will be skiing with another competent skier.
Thanks in advance for your suggestions!
This is a low snow year so far. It's snowing now, and we expect more in the next few days, by the time you get here, we should/better have good coverage in the Cottonwoods...Snowbird...watch the report and stay flexible.
If not, Deer Valley may be the call for two days skiing at your level. Lots of steep groomers that are screamingly fast, crowds are gone, and there's tons of snowmaking. It's real cold and the new snow folds into the manmade for a nice velvety consistency. Also, during the summer, the butlers remove rocks from the off trail stuff, especially the bowls.
If I were your I'd do full days at Alta and Snowbird and a half day at either Solitude or Brighton. If the half day is skiing to 2pm and then a flight, Snowbasin is a better idea. Except on a powder day, the terrain at PM doesn't compare to any of the other SLC resorts.
