That's the shortest route (distance) but the longest route (time)
to get to DTD you turn right out of SVR - then right again at 536/World Center Drive (becomes Epcot Center Drive after I4) then take the next exit after I4 to Buena Vista Drive and you are right at DTD's West side. A little longer drive (distance), a LOT less traffic, higher speed limit, and almost no lights. I would NEVER send someone up 535 to enter DTD via Hotel Plaza, unless they like sitting in traffic.
Here's a google map of the route. Note that SVR is A and DTD is B. The longer route shows as 2.5 miles longer, and 1 minute longer in time, but the upper route does not take into account the time wasted in traffic. The longer route has always been quicker for us (and more like 6-7 minutes than the listed 10 minutes).
