For one thing, my scheduled flight to Orlando doesn't even arrive in time. If most Summit guests are like me, they see Sunday as a travel day. In fact, I have a hunch that most consider their first mandatory event as being the 7PM Welcome Reception's free bar.
Free! Free! Free!
You must be there to win!
If you are less open to gratuitous enticements, perhaps you will attend just to learn how to improve your career by running successful BI application development projects. That works too.
