We live close to Youngstown Ohio and have driven to WDW many times in the past, on I-77 from our house, non stop except for gas its 19 hours, last trip by car we took the I-75 route and it took us 21 hours. We lately have been taking Amtrak to Kissimmee the drive has gotten to hectic now for us, we're now over 50 and the hassle of all the traffic the whole way is just too tiring, espically going home after a relaxing vacation at WDW and the by-passes around the big cities aren't a bargain either. Never have I seen so many cars, trucks and what not for the whole drive, its like bumper to bumper the whole 1100 miles, not like 30 years ago, when you seen just a few cars early morning or late night. Enjoy your trip and go slow and arrive safe.
