I live close to the Port and I would say the drive from the Port area to Universal is around 45-1hr. It is only 67 miles from our home and we are south of the port by about 25-30 minutes. It's a straight shot, across 528, which goes into the port and also to the airport/universal. Getting from the park to airport would be no more than 1/2 hour if they left before rush hour. With all considered they may be able to get 5 hours or so in the park.
