A side note to everyone in here who may be unhappy with their row or section, keep the faith. My family held season tickets to the Mets for years (we are gluttons for punishment), and every year more and more fans either had enough of the team or just couldn't swing it financially anymore and we would get offers from the team to improve our seats. We finally got to a good spot we were happy with and stuck it out there for a few years until it got too difficult to get rid of seats to games we didn't want to go to, and we all got sick of taking a bath on the ticket prices.
We found that the biggest leaps in seat locations came in the years when the stock market didnt do so well. You'll find companies and individuals who buy the seats to use as gifts for clients start to cut back expenses, and the team was good about offering those seats to current ticket holders looking to improve spots.
When you go to games, keep an eye out on the seats around you. If you see consistently empty seats that you might be interested in moving into, take note of where they are and call your ticket rep at the end of the season to let them know you might like to switch if the holder of those seats isnt interested in holding them any more. It helps the team out too by putting bodies into normally empty seats.
I'm sure the club is going to come up with some type of plan to avoid large swaths of prime and empty corporate seats, akin to what you find behind home plate at Yankees games.
