The Kennedy Center Tracking Order Status

Kennedy Center, sadly, has join the mandatory fee club (see extra "resort fee" when you're room rate is to stay, yes, at a resort). I was trying to save on my great splurge, a $289 seat at Bye Bye Birdie, by going to box office to purchase ticket. But no, there's no respite from the MANDATORY 10% FEE even if you go to the BOX OFFICE. Think if I was a parent trying to take three little kiddies and buying "cheap seats" for $150 each. That's $60, food on the table for some. Do they do it because Ticketmaster charges even more? Is there some tax advantage? Does it not get counted in Entertainment CPI? STOP IT.
