Lisa has a good point, it very well could be because people don't follow instructions. When I had heard there was only one entrance for BC Place, they made it sound like there was only one entrance for the entire ticket holders, GA and reserved, but it sounds like it was one entrance for just GA ticket holders. For Seattle they have one entrance for GA but four or five for reserved. Hopefully it goes smoother for those in GA and people have read the instructions ahead of time or perhaps they will have staff walking the line to remind people, but I do agree with Lisa, chances are a lot of people never paid attention to the rules of entry. I am so glad we are in reserved and don't have to deal with lining up several hours before.
