I was there during the Gay Week and it is not "crowded" like people say. I was shocked at how un crowded SWW was that weekend, lol. We didn't wait hours for characters. Darth Vader was the most and it was, oh no, only 30-40 minutes. Don't listen to people who tell you it's so crowded.
Oh and BTW, the store that sells all of the collectibles, yeah there was no line like I was told there would be. We walked right in numerous times of the day. It's really not that bad.
The line for collectibles is usually longer on the first day, since these are on a first come, first serve basis(they do not split up the limited editions between each weekend, if they are out on the first day, they are out). I know somebody on a different forum who stood in line for 3 hours for merch. Got to the front to find out the pin they wanted was sold out.
