I-95 it's 29 miles to Disney's HH resort.
From I-95 it's 20 miles to the bridge that crosses over the water to the island. From there another 9 miles to Disney.
The first 20 miles will be speed limits of 55, slowing as you get closer. Only about 3 traffic lights in this stretch.
After getting on the island, speed limits range from about 45 down to about 30. There's probably a half dozen traffic lights.
If you take the toll road, you avoid most of the lights, but then travel too far south, needing to turn back north again to get back to Disney, and hitting a few more traffic lights on the way. I think taking the toll road actually takes longer.
If there's normal traffic, it'll take about 45 minutes from when you exit I-95 till when you pull up in front of Disney's resort.
All this is if you're coming from the North. If you're coming from the South, there is a shortcut you can take, but the roads aren't that well marked.
Hope this helps.
