I havn't personally been but have been researching all things Star Wars Weekends as our trip is planned during that time but we won't arrive until the Sunday of the 1st weekend. From what I have found online (mostly here) the first weekened and first day of every weekend are busier b/c of the new exclusive merchandise that is available, but if you aren't there to get the goods then you will experience normal waits for stuff and above average waits for Jedi Training and Star Tours. Most of the SWW fans are standing in line to meet the actors or charecters and purchase merchandise, watch the parade and the day ending Hoopla show, they will visit the other things in the park but primarly are there for the SWW events. If your group can ONLY visit DHS one day and you want to do 'everything' I would recommend visiting on a Non EMH non F! day. You will miss Fantasmic but avoiding SWW, EMH and F! will get you lower crowds and less waits.
