When Prairie Sky did a previous survey it asked people if they would be willing to pay for a $50 annual membership to use it (Edmonton residents), didn't they?
At $50 a year, would that even need to be incorporated into ETS for the annual pass holder? I would not expect to buy an annual gondola pass and have access to ETS for that rate.
Now for someone using it one time and paying perhaps $8 or more, I could see them wanting to use ETS as part of that fee and not have to pay another fee in addition if ETS was required beyond the area covered with the Gondola.
But an ETS monthly pass holder may be willing to spend an extra $50 per year ($4 per month) for the added convenience and benefit of this service. And if not, someone could continue to commute how they did previously before the Gondola perhaps?
