Had these seats for the Jays game on Opening Day last year. They were playing the Red Sox and lost. Bummer. The crowd was lively as they are every Opening Day in every ballpark but Rogers Centre's attendances takes a dip once May and June hit.
526 is one of the better seats in the 500s since it's near home plate but that doesn't mean they're good seats. The players all look like ants from up there. You stare straight down at the field and have steep stairs to climb to reach your seats.
If you don't mind constantly referring to the scoreboard, you probably won't mind these seats. But the railing in between each row made things a lot more cramped than they should have been. I've never seen another ballpark designed this way.

The park itself is not that attractive. I think if you took away the roof and part of the outfield so that fans could see the downtown skyline, it would vastly improve the image of the ballpark but Toronto is cold in October and April which is why they have a retractable roof. There is quiet a lot to do in the areas surrounding the ballpark including the Hockey Hall of Fame on Yonge.
