NJ Goofy's answer doesn't take into consideration that you may stop at one or more resorts before being delivered to SSR. In general, DME will take anywhere from 60 minutes to 90 minutes to get you to your resort (the average is like 70 minutes). For planning purposes, I would use the 90 minutes to be safe.
FWIW, SSR frequently is the second stop on a route after OKW and before POFQ and POR. Those routes aren't set in stone, however, and can vary, so don't make any irreversible decisions based on that information.
