We go south on 75, but only take the Turnpike briefly to get to Hwy 27. Even though there are stop lights on that road and it's probably slower, we've always preferred to go down it than to take the Turnpike all the way to Orlando. In years past it was scenic with fruit and vegetable stands. Now it's mostly subdivisions.
If you take the Turnpike all the way down, go west on I-4. It's just a few exits to the Hwy 535 exit. It's the one marked for DIsney Marketplace. Take a left off the exit and Vistana is just on the other side of the interstate on the right.
