Hi Hans,
If we assume:
- 600,000 total visits per season
- Each annual pass holder visits 10 times on average
Then the number of unique pass holders is simply:
600,000 ÷ 10 = 60,000 pass holders.
So yes, it would be 60,000 annual pass holders under that assumption.
The only caveat: this holds true if all 600,000 visits are by pass holders and each uses the pass exactly 10 times. If some visits are from single-ticket buyers, or if pass usage varies a lot (some 3 times, some 20), the actual number would be different.
Best,
Evelina
