Perhaps I caught this thread too late for your trip, but if not maybe this will help:
We travel roughly the same mileage & direction quite often (Champaign, IL->Cape Canaveral, FL going again the 22nd in fact). If you can make it in 5 stops, I'd love to hear about it because that would make a huge difference and be worth the 90->100 upgrade. We always drive straight through. It's about 2-3 hours longer than a gas car depending on temp, but we don't really notice since autopilot helps a lot. If you can charge between 15% and 80% it will go fast. That last 20%--at least in the 90--feels like it takes forever. Our average supercharger stop is 33 minutes, but that is climbing since our charging speed is dropping with age. The 100 will do much better, I'd imagine.
Here's our list of stops:
- Mount Vernon, IL
- Kuttawa, KY
- Brentwood, TN (Nashville)
- Chattanooga, TN
- Atlanta, GA
-Tifton, GA
- Lake City, FL or Ocala, FL
- Orlando, FL (Turkey Lake Service Plaza)
You'll probably get to drop Orlando, FL and pick up Champaign, IL or maybe Effingham, IL?
I'd suggest ignoring the car's route planner and charging enough to go from Atlanta to Tifton rather than stopping in Macon. If you can bypass Brentwood/Nashville somehow, that also saves some time since it is out of the way.
Lastly, if you head to the coast from Orlando and need to charge, we have a 14-50 you're welcome to use.
