I will be attending a conference to give a presentation in approximately two months. I would like to buy plane tickets to and from the conference location, especially because I am living outside the US and the conference is in the US, so travel to the conference is not an easy thing.
Unfortunately, the conference organizers have yet to confirm and announce the conference schedule. I do know that the last possible presentation session ends at 2 pm on Tuesday, so if I wanted to book plane tickets now, the earliest flight that I could catch would leave at 4 pm. However, if my presentation is on Monday, I might prefer to book a flight that leaves early on Tuesday morning, skipping some of the sessions at the conference.
Question: Should I book my flight tickets now at "safe" times? Or should I book my flight tickets, leaving early on the last day, hoping that I don't get scheduled for the very last presentation slot?
Response to answers/comments: I don't need to leave early. I have just often observed that at every conference which I have attended in the past, the attendance at the last few sessions is rather low, and it just seemed to be "normal" to leave early. Based on the answers/comments, it seems that just because many others leave early doesn't mean that I need to when I can stay at the conference, learning things and meeting people.
