I think the gondola is a bit of that 'can't judge the demand for a bridge based on the number of people swimming across the river' type deals (did i phrase that right? it's a Brent Toderian thing). Right now, getting to Whyte is rather tricky, just a lot of people put up with it ('swimming across the river'). driving there is a nightmare, and we don't want it filling up with parking lots to fix that. Buses run down it, but to get to one of them you have to transfer at U of A (or Bonny Doon soon, but that's an even farther haul to the fun area). biking is decent, walking mediocre.
To walk/bike, especially when coming from downtown, the Valley itself is a huge hurdle. you either cross at the High level, which makes you travel west to the edge of downtown, then dumps you out at the West edge of Whyte Ave, meaning a lot of extra walking to go from a major transfer like Corona or Churchill Station to say, the farmer's market; or you have to take the Walterdale bridge, which involves a long walk down into the valley on the north side with subpar sidewalks, and a hike up the south side on some lovely -but very steep- trails. None of the options are accessible to someone with mobility issues, and honestly are beyond what most people would have the wherewithal to undertake in any sort of inclement weather.
Transit could be improved along Whyte Ave itself; but the issue remains that crossing the river via transit will only dump you at one end of the ave or the other, and then you have to move along it to get to your destination. This inconvenient routing is a non-starter for a lot of people, they'll either drive, or not go at all.
The point I'm meandering around here is that access to Whyte Ave isn't as good as it ought to be, and i think there is a lot of pent-up demand and potential for growth in connecting the key points, the actual centers of DT and Whyte with something direct. it wouldn't just be a novelty; there are lots of people looking to go to Whyte, but don't do it often because of how difficult it is currently. if a system allowed you to take any of the LRT lines into DT (which will soon be much easier for a lot of people to do) then make a simple transfer to something that gets you to the heart of Whyte in 10-15 minutes, that would be huge. I mean, there a people who commute via ERRS in the summer. if people are going to the lengths of relying on a 100-year-old streetcar to get to work, there must be demand for a more robust connection between the two areas,
