One day trip for Star Wars weekend...May 15th or 22nd?

[love disney]

Will have one day left on a 3-day ticket and plan on hitting Star Wars weekend this May. We will go for a Friday, but we aren't sure if we should go opening day, May 15th, or the following Friday, May 22nd. We want to pick the least crowded of the two days and aren't sure which that might be...the 15th is opening day which might be pretty crowded, but the 22nd is the Friday before Memorial Day as well as the 24-hour event at MK. Any thoughts as to which of the days would be less crowded? (I know Star Wars days are crowded anyway, just trying to pick which will be less crowded.)
Thanks!

The first weekend will have Ian McDiarmid vice Warwick Davis the second weekend. I would say that the opening weekend coupled with the great celebrity would make the second weekend the better choice. Plus with the 24 hour day, a lot of people will probably be hanging out at MK that day.
