8 people, 4 ski days.

Dec 29 – Jan 3 — drive up the first day, ski four, drive home the last. That is New Year week, so every pass below is counted against the days it will actually scan on.

Pick the mountain. The pass is the cheapest 4-day access a 21-year-old can buy there, the houses are the ones near it, and the number on the right is what you pay.
