I am not an expert on your market but I will give you some advice that should apply well tov most any market:
1. Do everything right: To include but not limited to pro photos, professional quality design, durable furnishings. Don't skimp.
2. Look where to add value. Again I am not an expert on CA ski area but I imagine hot tubs are popular amenities. See what the most popular listings in your area are doing and emulate it. You do not need to reinvent the wheel.
3. Get on at least Airbnb/VRBO. There are other platforms you could do to boost but at least those 2. Take advantage of their boost feature to raise visibility in exchange for discounting new guests.
4. Pricing - If you cannot check your competitions price and adjust yours daily you may want pricing software (PriceLabs probably best for single listing owners/operators). Most markets are competitive and a mere $10 a night could cause someone to book another property over yours which could cause vacancy and loss. You also do not want to be too cheap and leave money on the table.
If you do all of that you will be well on your way to being successful. Good luck! :)
