Prepare to be ICEd.
I had to stop here again today to recharge after a long trip to/from north/central NJ. Even without superchargers, this is a very busy rest stop, and to add insult to injury, the parking lot and the flow of people in the building are horrible. Absolutely no thought was put into how cars move into/out of a parking lot, or how people move into/out and through of a building.
Today it was *very* crowded, and when I arrived, 2 of the 4 spots were ICEd, since there were no other normal parking spots open. While I was there, those two cars left, but two others moved in. Another MS showed up and took the last remaining open SC spot (lucky for him there was one spot left open!). Another 5 minutes, and it too would have likely been ICEd. I don't think there's anything TESLA can do about this -- there's just too much traffic and parking demand at this location that ICEing is likely to be a persistent problem.
Also, the building itself it a horrible design. There is just ONE normal sized door on the side of the building, and when it's busy, this is a massive chokepoint, blocking people from getting in or out easily. It should be at least a double-door to allow a flow in and flow out of people. Once inside, though, it's worst, since there is only one narrow channel of space to get through the store shelves.. then there is a line of people waiting to pay for their stuff you have to get through, then there's another like of people waiting at Dunkin Donuts you have to push through (you can't go around).. then ANOTHER line at Subway... THEN, at the FURTHEST POSSIBLE POINT from the side door, are the restrooms, where most people are trying to get to. Then you have to fight all the same lines/crowds getting back OUT Of the building. I just don't know how anyone could design a building so poorly, and these are the brand new designed building for the Merritt Parkway rest stops. I think if they had just but the bathrooms near the doors, it would alleviate 90% of the traffic problems inside.
Anyway, just be aware that this is a very busy and crowded place, and there's a good chance you might have to wait for a SC to get de-ICEd.
