I live in Vancouver. I imagine rehearsals will take place in the old Pacific Coliseum. This is where they rehearsed the I&E tour and also where I saw the best concert of my life (arena Zoo TV April 1992). BC Place is a stadium and the local soccer team plays and they will be using it till mid April. Also a lot more expensive to rent a stadium then a unused arena. My bet is the band rehearses at the Pacific Coliseum and then take over BC Place to build out the stage a 1-2 weeks before the first show.
