The only place I don't like to sit is in right field past the Pesky Pole - the seats face towards the Green Monster and you need to look left all game to see the infield. Also, make sure your seats aren't obstructed view, else you may have a pole in your line of sight to the field. The only other thing to look out for is that there are a few dry sections in left field - no alcohol allowed. Other than that I would say there are no bad seats at Fenway, just a matter of how much you want to spend.
Go Sox!
