Specifically exit 71. Take a right onto Central FL Parkway, then just follow the road until you see the killer whale statutes on your left (should be the third stop light). 15 minutes seems about right.
Parking is $11.
Not many decent restaurants in the immediate area, but on your way back, if you stop off on 535 (the next exit west on I-4), you'll find everything imaginable. You can then get back to SSR using the WDW entrance across from Crossroads.
