If members from outside British Columbia are going to go, my preference is to do it mid-week. I'm here Monday to Friday; I see my family on Saturday and Sunday. If I go to Vancouver on the Friday, I certainly will not be seeing my family on the weekend, because it's not possible for me to get back from the west coast.
Maybe we could do it on a Thursday, which would allow you to stay through the weekend. Alternatively, I'd suggest Monday. A Monday might be better, because then at least members can get to Vancouver on Sunday, attend the meetings on Monday, and then take the red-eye back to Ottawa on Tuesday.
