It took us about 20 minutes or so from cabana bay to Disney springs at about 10.30 am a few weeks back and about 30 mins to get back from the halloween party at midnight, I can't help much with the early morning traffic though. If memory serves me right I think when we've done the drive from all star resorts to universal in the past its taken about 20 mins and we normally leave at 8am but I haven't done it for a few years
