It depends. If you get to the bus stop, only to find out that the MK bus jsut left, then it's going to be at least 20 minutes before the next one. On our last trip, we were waiting at the bus stop for a little while when an Epcot bus came. DH asked, should we take that, then take monorail to MK? I wasn't sure. Then right behind it another Epcot bus came - so we hopped on that one - Epcot is much closer to SSR, so it didn't take long to get there. Plus the kids(and I) love riding the monorail, so we had a nice relaxing ride on the monorail to MK on our last day.
