Not directly, but there are possibilities with a small detour - e.g. junction of Sand Lake Road/John Young Parkway, a newish one of SR 535, one on US 192.
Given where you're coming from and where you are going I'd suggest the one on SR 535 just past the Lake Buena Vista Outlets. Pretty easy to find if you're taking the 417 from Sanford as this takes you virtually to WDW.
Stay on Highway 417 until you see signs for SR 536 (W) (I think they also mention WDW) and then join the 536 (W) for a short time (2 miles or so) - this is the route to the Contemporary in any case !
Turn left when SR 536 intersects SR 535 and go south. Pass the LBV outlets and
WalMart is on your right. It's huge !!!!
Simple to get back to WDW from Walmart. Turn left out of WM back onto the SR535 heading north and then left again at the junction with SR 536. This takes you right into the World.
