You have received your syllabus for the OGS conference and you are trying to figure out how to be in two or more places at once. Not a problem. Relax. There are solutions.
If this is your first conference, you will want to see, hear, attend, and buy everything. Three and a half days of lectures, shopping, banquets, networking. Unless someone came with you to drive you home after the conference you cannot possibly do everything. I literally walked the soles of my shoes off at a conference in Cincinnati. I am sure I left a sole train (sort of like Hansel and Gretel) everywhere I went. I pitched the shoes in a trash bin on I-75 on my way home. I probably should have brought them home and buried them in the back yard as a tribute to my ancestors.
So what do you do? Pace yourself, pick and choose. This is where your syllabus comes in. You will see that there are five lectures scheduled for every time period, and you can only physically attend ONE. Chances are that you will not want to attend all five. Maybe two or three. You want to look in your syllabus for the handout that goes with each lecture. There will always be some that will give you the basic information you need. The process of elimination will take you to the lecture you need to attend.
As for banquets and events, once again pick and choose. Pace yourself. Remember that a conference can become a four day marathon if you are not careful. There will be other conferences so don't try to attend every lineage society banquet. But, do attend the society luncheon and business meeting.
As for over-shopping in the Exhibit Hall see the previous post.
