The actual ride takes maybe 5 - 10 minutes. I've never timed it but it doesn't seem like it was more than 5 or 10 minutes. But, the boat is not always at the dock so there can be a wait for it to get there and sometimes they wait a little while before they leave the dock in case others are coming to ride. Depending on your walking speed, it probably takes 20 or so minutes, at least, to walk all the way to the Studios. Actually, the boat docks at City Walk so you still have a short walk across the bridge to actually get to the Studios. It is probably quicker to walk to IOA because the path comes out at Margaritaville which is closer to IOA than the boat dock.
