At those ticket prices, it's very likely that they could survive on only a single tour bus full of people each day ... and they'll probably get more than that (not a lot more, but "more").
Each single bus load of tourists will generate approximately $1650.00 in ticket sales, plus whatever food, drink, and trinkets they can sell to those visitors on-site.
Let's say (for argument) that each bus load of visitors will bring in $2000.00 in clear revenue.
That really only means that, at least during the tourist season ... 5 bus loads each day will bring in $10,000.00 in revenue.
There's also a pretty good chance that those 5 bus loads will be well sold out in advance too, as part of a much larger tour group package of attractions.
I think a low-tech tourist attraction with very few moving parts, and what is likely a very low overhead in terms of the need for facility staff, could make a good go of business with revenues of between $5000.00 and $10,000.00 per day.
And if they manage to develop themselves internationally as a targeted destination attraction ... they could easily double or triple those numbers based on the total number of tourists we have moving about Vancouver Island as part of an organized tour group during a typical season.
But I'll never go ... heck, I rarely even stop at the free view points near-by ... so I (and most people I know) definitely aren't the metric this attraction is aiming for.
