Listen, you will be fine. Just think you will be there in a little over 2 hours. Just keep thinking about how much fun you are going to have, in orlando. Take a book , some word puzzles or some form of entertainment just for you. A portable dvd player? Or a handheld game. Can surely pass the time. Before you know it you will be landing in Orlando. Just take a deep breath, and relax. You will be fine. No worries

Just think you wont have to drive for 20+ plus hours. I surely wish you a magical vacation!!!
