You would obviously know that there is a Supercharger at Woodbridge a few miles south of Lorton, I would charge up there before loading your car, then you can easily make it to Port St Lucie from Sanford. Also, the Ft Drum Station would may be up by then also. But Turkey Lake SP will be quite out of your way from Sanford. I thought of the Auto Train when coming back from Mass in Oct. But the drive wasn't difficult, the thought of it being free was nice. Also would rather be driving my MS than sitting on the train for 19 hours. You could probably drive from where you are to Jax by dark, then straight on down to FLL, saving time and about $800.
