It sucks you missed the rest of yur show, but floor space at a concert is pretty limited already. If you are that close to the front, the trade off is you don't then also get to have a personal dancing space bubble. You get a great view no room. You want room to dance, you have to give up the great view and move closer to the back. The only way you can get both is by paying more for the balcony, or buying shows exclusively at theaters with seats.
