We are actually going to stay slopeside either at snowbird or Alta (prob snowbird because lodging at Alta is so limited and the dining options look less appealing).
The private lodges in the town of Alta are not at all like most other lodges in N. America. Except for Snowpine, they include meals as part of the stay. Not just basic meals either. Full hot breakfast and fine dining dinners. There is only one restaurant at Snowbird that can match the level of dinners available at the Alta lodges.
Note that although Alta is a town with a mayor, it's not a "ski town" in the sense of Banff or Park City. There is a Town Hall, a Community Center, a Post Office, a police department, and a fire department, but no shops that aren't in a building of one of the private lodges.
Snowbird is a destination resort. There is a purpose-built "village" that has a central base and a second base. Most Food & Beverage is owned/operated by the resort on mountain and off.
I've stayed at Snowbird and only skied Alta. There is free bus service between the Wildcat base of Alta and Snowbird. Someone who is staying at Alta and has the Mountain Collective can start at Snowbird in the morning, spend the day there, and ski back to Alta via the Baldy chairlift out of Mineral Basin between 3:00-3:30. Of course, cannot ride up an Alta lift without using a MC day. The reverse is not true for people staying at Snowbird because after going through the Alta/Snowbird gate at the top of Sugarloaf (Alta side) then must ride up a Mineral Basin lift to get back to the frontside of Snowbird.
And good to know about the mountain tour at Snowbird! I looked into a private guided tour for Alta and it was like $600 for 3 hours…ouch.
The "private guide" at Alta isn't a Mountain Host tour. It's a guided lesson with one of the more experienced ski instructors. Typically that means skiing off-piste essentially the entire time. Same as having a private lesson, but the emphasis is on skiing with perhaps a technique tip or two if the guest asks for help. If not, the instructor will just go find the best snow after getting a sense of the ability level of the guest(s).
We will be arriving Thursday morning (plan to ski that afternoon), and leave Sat night. As of right now I’m thinking Alta day 1, Snowbird day 2, then play it by ear on day 3 depending on what we enjoyed more (and what the conditions look like.)
Sounds like a reasonable plan.
Given that the last day is a Saturday, keep in mind that you could ski both Alta and Snowbird. Depending on snow and road conditions, there could be locals on both mountains. Getting a head start to ski Mineral Basin by getting in line to load the tram early might be worthwhile. Or just take the Peruvian chair and go through the tunnel. When the lines get long for the Mineral Basin chair, then head to Alta for a while. Just remember that to ski back, need to be loading Sugarloaf by 3:00 to allow time to ski down to the MB chair before it closes.
Or plan to take a bus from the Wildcat base back to Snowbird. Note that buses after 4:00 can get full.
How do you plan to get up to LCC? Shuttle or driving?
