I agree with your route. You will encounter heavy traffic on I4 in the Orlando area, just be patient. As for weather in the mountains, just watch the forecasts for a couple of days before you leave. Hopefully you have allowed an extra day or two in case of weather delays. It is better to be parked at home or leave a day or two ahead of schedule if it means avoiding driving in freezing rain or snow. That should only be for the first day of your trip.
If you do arrive early, call reservations, they will probably get you in early (November).
