This is Scott Rudin playing games. He did the same thing with Dolly and there was plenty of availability during the run. My 5th row seat dropped from 499 to 199. I just checked tix for Mockingbird during the holiday week with the replacement cast and virtually the entire orchestra is 450. If you are flexible on dates I would wait to see whether it is even a good production. Producers ought to support people who are willing to buy a year in advance instead of trying to take advantage of them.
