My gf (non-gamer but loves fantasy books and medieval stuff) and I went last year and had a blast. The two dueling comedic swordsmen are a riot. The guy doing the tightrope act was very good (over shark infested waters to boot!). The joust was a treat to watch, the guys teaching "proper English jousting cheers" are very good. I got a kick out of the glass blowers since i love watching craftsmen who are good at their work. I got some chili in a breadbowl (it was cold that morning) that was really good, first time in a while i have liked on site food served at an event. The vendors had some really nice things, bands roam the field, I got a CD from the Vic Daniels Quartet that I like to listen to as I surf.
I would definitely make the trip if you live in the area.
