@Telemark Phat they love their Daytrippers because they like being able to expose them to the CP experience, oversnow and all. Also it's the prospect pool that they develop their weekly customers from.
You can buy more Daytrippers. It's just that you would be charged the extra $5.00 for the RFID card each time until you have a card and can load the extra tickets on to it.
The challenge CP have over other resorts is selling the oversnow and the level of lunacy people will go to to get their times booked. It's a complexity not many other ski resorts in the world have, so developing the ticketing and webshop to accommodate this has been challenging. Particularly when most of the ticket sales were made in their original system.
It's pretty well sorted now, however there are a couple of clunky bits that we'll get ironed out as we progress through the season.
