<p>The problem with not going is this: You’ll never know what you missed. </p>
<p>No one here can possibly tell you whether or not, for you, this would be worth $X, because (among other things) no one here can know exactly what your experience would be like. But another, and perhaps more useful, way to frame your question would be this: Would I rather spend $X on something, taking the chance that I’ll later feel that it wasn’t really worth the money, or not spend that money and be left forever wondering “geez, I wonder what I might have learned there, who I might have talked to, etc.”?</p>
<p>(P.S. Obviously I don’t know your circumstances, but I wouldn’t be surprised if, with some ingenuity, etc., you could figure out some cheaper way to get yourself there and back.)</p>
