Take the bus from Saratoga to MK. Ride monorail from there. You can hop off at resorts and explore or just do the loop.
Take the bus to DHS and ride the Skyliner from there. We rode the Skyliner from DHS over to Riviera to check it out. If you want you can take the Skyler to EP also.
If you are looking for transportation to a park from SSR, it's the bus or Uber/Lyft.
