We have booked a stay in Universal the week after Christmas. We have 2 adult drivers and two kids. I'm trying to figure out the best time to leave to avoid traffic in Baltimore/DC. Since it's winter I'm guessing it would be best to stick with 95. Also any advice on where to stop and what to avoid would be appreciated. We plan on making an overnight stop. South Carolina I think, I want to book a room early. Also where is the worst rush hour traffic from SC into FL?
