Well, last night (Sunday Jan 29) we took the chance and drove to Birmingham to meet friends, and would need a charge to return to Montgomery. After driving around a couple of parking lots and not finding the charger, we looked at the nav map again and saw we were on the wrong side of the complex. Drove around, then found them easily. No one else there. Is that a bad sign, I thought? Deep breath, plug in, and...success! We headed out for Octane after the charge rate passed 275 mph and was still climbing.
Tesla nav says it is still down, but not for us. What a nice area, too.
The superchargers are in the valet parking area of the lot, and I think that's a good thing. The area was hopping last night, and all 4 parking areas we saw were 99% full. If the SCs had been in an open area, that would probably have encouraged icing.
Access getting around the streets in the area just a bit awkward, but not too bad. Folks at Octane were friendly and welcoming, looks like a number of good places to eat.
