It is as you said 6 one way, half a dozen the other. If one approaches the chargers with the Westfarms Mall on your left, the angle of the lines, works. If one is coming from Rt 84, despite what the nav system tells you, you have to approach the chargers by going through the parking lot and turning right, behind Red Robin. This makes it difficult to back in, if there are other cars there. If no one is there, you can swing in, getting out of traffic's way.
Recently I was returning from the Danbury area, heading East on 84. I decided to use the nav system to see how it wanted me to get to the chargers. The nav system wanted me to pass the entrance to Corbins Corner and turn left just beyond Red Robin.
Problem is, you can't turn left. That road "legally" is only accessible for traffic coming from the other direction.
Just a little trick to pass along to those charging and looking to get back on Rt 84 East. When finished charging, pull away and drive on the back road, that goes behind the plaza. Since your car is already pointed in that direction, it is much more convenient. This saves you having to deal with traffic lights and obviously traffic. The "access" road will bring you out behind Sears Automotive. You just turn right and you will be in the proper lane for the RT 84E exit.
