Which mountain is the anchor? If you cannot answer that, your lodging search is premature.
What does your pass actually cover? Tahoe's pass geography can make the base decision much easier.
Weekend or midweek? Palisades and Northstar parking systems matter more on peak dates.
Will you use transit? Tahoe City, Truckee and South Lake each become different propositions when the car can occasionally sit.
If Palisades is the priority, have you compared Olympic Valley? Sometimes paying more removes the weakest part of the trip.
If Heavenly is the priority, which base will you actually use? Gondola convenience is great until weather changes the plan.
Will you really ski both sides of the lake? One deliberate crossover is reasonable. Repeated crossings deserve suspicion.
Are you ready for chain controls? Tahoe winter driving can change quickly, and the vehicle setup matters.
Does the property parking fit your vehicle? Snowbanks have a habit of making generous summer parking spaces less generous.
