I went today. I wasn't really planning to after I slept until 1PM but I figured it was worth a shot. I got there around 2:25 and was around 115th in line for session one (Hardy, Braun, Weeks, Torres). It was very well organized and kept orderly by the team employees. According to one, the first person got in line at 8:45AM. The session one line was cut off at 3:00PM. Autograph tickets were handed out around 5. Everyone had to wait in line in the concourse but the signing was held in the usual place in the Fan Zone. I'm not sure if the session two (Hart, Gallardo, Riske) tickets were all given out by 5 but if they weren't I'm sure they were taken by the people at the front of the session one line after they got their autographs. I'm pretty sure you could have gotten there around 5PM and still gotten a session two ticket. I got Hardy & Braun on 8x10s, Weeks on a bobblehead, and Torres on a mini helmet.
