There are sidewalks. Other than that, sure, you can walk it if you don't mind a relatively long walk alongside a very busy road, as well as walking across the beginning of an entrance ramp. I'd walk to DS from Bonnet Creek if they'd put sidewalks in though, so I'm fine with walking.
You can do a Street View on Google Maps to see your walking path. Just follow along as you move down the street. You can even click on the little walking guy when you get directions to have it show you the walking path. It's about 2 miles, give or take, from the hotel to Disney Springs.
