I love structured plans too, and GT has them. I will pick up my first guitar ever tomorrow and get started in the Beginner's series.
The other good part of GT is that you can slow down or rewind a lesson ad infinitum, try that with your face to face instructor.
Hang in there, and you'll progress. I know, I did it with bagpipes. With time, good instruction and dedication, you can learn to play an instrument.
