The day session ends when the last match on the schedule for the day session ends. I've been to many tournaments where the play is interrupted (ususally by rain) and the day matches go past the time of the scheduled "marquee match" of the evening session. Which is a bonus for night session ticket holders. If things go too long they sometimes hold matches over until the next day. But I think you are right, they admit night session goers after 5pm.
Hey, it's one day closer...I'm getting the fever. Maybe I'll go to quallies on Sunday.
Thenman - I agree with you, the early rounds are the best; you can see more players and I like to see the new faces and some of my favs are lower down the ranks so if I want to see them the first round is the best bet.
Really wish Rafter was playing though. He always has a good tournament in Canada. If he enters next year I'll head for Montreal for sure!!!
