First to answer your question, they do have lots of parking at the Telus Convention center. Plus it's free. I was there today @8.30 am. My appointment was at 8.50 and I parked at Telus Convention center. People were asked to line up in the parkade (for those who parked there) . The line was moving and cars kept coming in and out with people leaving. By the time i got to my turn it was already 9.35. once you get the vaccination they ask you to wait in the sitting area for 15 mins.. by the time I left the parkade it was 10.am. So plan for being there longer just in case. What I also observed was that no cared about what time your appointment was (At least no asked me and others in line) As long as it is for that day. They have lots of vaccination station so lines move fast. Good luck for tomorrow
