Don't be discouraged! Since you got your first taste of the crowds, you'll need to ask yourself next year "Why am I here?". That will determine how you approach the event. If you are looking for autographs be prepared to spend most of your time in line and have a backup plan (another autograph line) if you get there too late. New this year (for me at least) was the IMs from the Reds with the times/personnel for the autographs and photos. So instead of standing around the central booth-the info came via phone (rates applied). Twitter was helpful as well.
I started going to Redsfest in 2000-then it was held in January. This was after the Bichette and before the Junior trade. It was also snowing (not much). Even then the autograph lines were outrageous and you'd see people with large duffle bags worth of merchandise (side note: this year noticed that there was a sign limiting the size of bags). So I concentrated on photos and for the next couple of years that's what I gravited to. Also, in the early years it was pretty much autographs, photos, Main Stage (still have fond memories of Richard Hand and his tape recorder ), and memorabila. Not much kids, vendors, or interactive stuff.
