Personally I wouldn't shift things around just to move from cat 3 to 2. You will be in the balcony, but all the tables in the balcony are along the railing and you should have a good view of the show. Plus, the performers mingle with guests and a couple do come up to the balcony, so you have just as good a chance of getting some interaction. I've sat in the balcony and enjoyed the show just as much as on the floor, with the exception of one time we were lucky enough with cat 1 to get right next to the stage. That interaction was amazing. But I'd stick with the cat 3 if it were me.
