Hey Waleed! Being a commuter is not a big issue, you can still enjoy Welcome Week! Events happen for the entire week and go all day long, with some events happening in the evenings.
Check out the welcome week schedule for each day, and make a list of which events sound like they interest you most, and then try to drive down and be on campus for those events.
Here is the schedule and info:
When parking, try to avoid parking on campus since it's usually chaotic (and expensive) to park in the center of campus near the Student Centre. You're better off parking on the local streets nearby where there is day parking (not 2-3 hour limits) and then walk 5-6 blocks to campus so you can enjoy the day and not worry about your car and getting a ticket.
Welcome Week is a fantastic experience - you won't want to miss it!
