This seems to be an issue mostly at the more crowded times of year. Even when we were there over Thanksgiving, well, from the week-end following T-Day,...the shows weren't so crowded that it made a difference. Philharmagic seemed to be the worst. We also like to sit more toward the middle. Our strategy?? We sit toward the back of the theater. Most people don't seem to like to sit back there.
However, when we have been there and it is crowded, and people insist on sitting plop in the middle of the row...we excuse ourselves as we tromp on their feet....'oops, sorry about that, oops, sorry..just trying to follow the instructions..oh, sorry..was that your foot?'
It always amazes me...there are really no bad seats in these places. And those that have moved on down the row, as directed, are the first out. It's incredible to see those that have insisted on sitting smack in the middle, making the rest of us crawl over them, try to get out first..past those of us that had to climb over the squatters to get to our end of row seats. You would think that they would learn that those end of row seats exit first. Now, that's a primo seat if you ask me!!!
