Sandy is a suburb of Salt Lake. Staying there will be, well, very suburban. Lots of strip malls with chain restaurants and stores, small office buildings, parking lots, etc. If your routing to the resorts includes any travel on I-15 in the morning, you will hit rush hour traffic. The bus would be a great option, provided you are directly on the line the travels east towards the mountains. The bus ride might be close to 30-45 minutes.
One potential pitfall could actually be snow. When a big storm comes through, they will often close Little Cottonwood Canyon for avalanche control work. There is just no way to predict the weather and there are other options like Big Cottonwood Canyon or even Park City, if that were to happen. Just a thought.
