Replying to UBC Students

Almost definately gonna be going to UBC for engineering this fall and figured I'd throw out a few skiing related questions I haven't found adequate answers for and see if any of you guys who go/have gone there can answer them.

Do you need to have a car to get to north van/whistler to mtn bike and ski often or is it easy to find homies to carpool with pretty much any time?

Is it realistic to go to whistler every weekend (considering I'll be in engineering) or will I be too busy and have to stick to the locals most of the time? I'd be willing to make a lot of sacrifices to other activities to make it happen

Grouse vs. Seymour? I got the vibe that cyp is a bit of a kook hill, but tell me if I'm wrong. Grouse seems to have a better park and is closer and you can take the bus, but I've heard it's crowded and the natural terrain is bad. Seymour's park looked ok, but their jumps looked to be stepdowns which I don't like and then a bunch of short down rails, but I've heard the natural terrain is better and the vibe is more chill. If I can go to whistler more often I'd only really care about night park but if I can't I really want fun natural terrain.

Thanks!
