I attended in 2019 and will gladly share my thoughts on the experience.
First of all, Prospera Place is a small arena. You will get a nice view of skaters even from the back rows (where I was seated). There was some type of curtain on the top level separating the skater warmup area from the spectator area-- and I noticed one fan trying to peek around it.

Please don't do this! One could also spot the Japanese broadcasting team on this top level. In general, I thought it was a good arena for this type of event.
I lost my gloves at one point during the competition. I was able to go to the box office and a helpful staff member returned them to me!
There were long lines getting into the arena (probably due to Hanyu's presence), but they moved efficiently. Security guards searched bags and removed food items. Thankfully I had stashed some snacks in my jacket pockets, so they didn't throw out all my snacks.

The food at the arena was standard arena food. I got a churro at one point and it tasted...like a churro.
Prospera Place is right next to the waterfront, so it's a good idea to walk around the harbor during breaks or ice resurfacings. There's a statue of the local lake monster Ogopogo nearby and it was fun to take a photo of it!
I enjoyed the scenery in Kelowna, although I worry that its scenic value has diminished since the wildfires there a few years ago. Renting a car would have provided me with much better access to nature and a means of visiting the wineries, although I am a tea person, not a wine person. Speaking of tea, there's a shop called Chaibaba near the arena where you can get some good teas and tea accessories.
I unfortunately can't say anything about the hotel situation, as I stayed in a cozy trailer at an Airbnb on the opposite side of Lake Okanagan.
The airport was nice (it has a Tim Hortons!), but I only flew out of there to return home. I got to Kelowna via a five-hour bus ride from Vancouver because bus prices were cheaper than inbound flights. The scenery along the way was gorgeous and I would highly recommend it if you're willing to take a bus!
(P.S.-- If any of you decide to go, could you please tell me if the Pooh bear in the box office is still there, out of curiosity? Thanks.)
