Followed along last year as an online NOLA friend struggled to make out her personalized schedule - it was a tough job for her, but I found it tough to be overly sympathetic :D 

Karen ... the music runs a total of seven days over the 2 weekends - 1 = Fri, Sat, Sun .. 2 = Thurs, Fri, Sat, Sun .. pretty sure they were 8hr days 
Mike .. seem to remember an even dozen stages on the charts last year but ??

Dept of 'for-what-it's-worth:
Just for giggles I looked for a time share exchange last year in mid January - nothing .. hotel room for 4 people near the fairgrounds - nothing.  Was told by one nice man that many people book the next year when they check out . . and that newbies should find and book the convenient locations at least 6 months out.
