So right off the bat, I am a fan... since this new Cell Phone Lot is much larger and accommodates more cars than the old one. The lot isn't completely finished since it looks like there should be even more spaces added when they are all through - I say this only cause I notice the temporary construction jersey barriers and an arrow painted on the road directing you to hit them head on.
Aside from more spaces, I hope they plant some large trees and maybe add benches like the old lot so you aren't idling in your car.
Warning, to get back to the terminal, you gotta go through a round-about.... I dunno about other folks, but I have no problems negotiating roundabouts..... unfortunately, seems like this conglomerate mix of drivers that have settled in Charlotte from different parts of the country, tend to not be as comfortable.... so just be cautious.
The cell phone lot also shares the same "new" entrance to the Long Term 1 Parking lot.... so I can see where it can be confusing... hopefully they put some better signage up in the coming months. If you find yourself in the right-hand lane going through gates (take a ticket, etc) you are not heading to the right place.
