I did it once and found it to be very worthwhile. Are you familiar with the process? You need to be nominated by a senator and they submit a form. You need to bring in all your own equipment so we opted to use wire stands and stand and play instead of trying to bring chairs. We played a program of mostly patriotic music and closed with Texas our Texas. Lots of great photo opportunities and we live-streamed the concert so parents could watch. Before the concert, we took them to Mozarts Coffee Roasters for breakfast by the lake. Very enjoyable day.
