I don't know much about the faculties, except that your degree says "UBC" not "UBC Okanagan" and thats wicked. It's way easier to get into and while the degrees offered are fewer, and Bsc. will still look like a UBC Vancouver Bsc. I digress...
The campus is fairly small, but the all still building (More rez buildings and likely faculty buildings in the future. They have a fair bit of land) The campus is laid out fairly well, its almost all brand spankin' new and is quite nice to be honest. Laid out on the edge of town in some rolling hills. One good thing if you are from out of town is the you could probably spit from you dorm window and hit the airport. Seriously its a 45 second drive in a cab or bus.
The problem with the campus is that it is a fair ways from downtown. If you didn't live on campus you wouldn't need a car, but you would want one. It would be a 20-30 minute bus ride (was there in July, can't remember exactly, was pretty hungover from Wakefest). Another thing is that sucks for going to the bars, but thems the breaks.
One good thing about the location is that it is closer to both Big White and Vernon (silver star, altough that is a fair hike) than being downtown Kelowna.
Kelowna also has retardedly hot girls. And so fucking many of them. A family friend's son just started 1st year there and is in rez. I ran into his parents (I know them better as this kid is 5 years younger than me and I know his older brother) and his Dad said that he was going nuts cause besides his roommate, the rest of the floor was girls. Apparently the ratio is like 70/30. That's reason enough to go there. Plus Kelowna is a fun town.
Sorry I don't know much more about the academics, but the admin staff there are quite helpful and pretty laid back. I'm sure you could give them a call (probably not best right around exam time or add/drop time) and they could give you tons of info and send you out some information packages.
