3D Experience World

This will be my first 3D Experience World and I just had a quick question.

I know it's a ways out still, but was just curious for planning purposes. As 3D Experience World is Feb 23-26, is it an issue if I can't make it Sunday (23rd)? I am planning on buying the whole package and would be there right away Monday morning (24th), but was wondering if I would be missing out on anything important that first day? Or isn't this really an problem to be concerning myself with?

Let me know your guys' thoughts.

Thanks,

Justin
