It's only about 25 minutes from the Pop Century area, which is where we usually stay. However, don't go on I-4, or you can get caught in traffic. We try to take Turkey Lake Road, which is behind Universal. Look at mapquest, and try to use side streets, rather than the busy expressway. Unless you are going during off-peak times (non-rush hour).
Also, last week, we came from AK to the outlets that are just north of Universal. The GPS said it would take 11 minutes, and it wound up taking about 15. But this was a 6:30 pm.
