For what it is worth, I first attended a Star Wars Weekend about 3 years ago and it was a great time with big enthusiastic crowds. A friend visited this past year for the first time and thought it was wonderful.
@Andrew C asks if Star Wars Land is not better than Star Wars weekends, and my response would be that Star Tours has already been in the park for many years but when Star Wars Weekends are going on, the whole area is enhanced in a positive way. I'm sad to hear the special event has been canceled even before the land area will be ready to open.
