I loved SSR so much i bought 160 points there in May. We stayed at the Springs which i thought was great. Walking distance to get coffe in my mug while waiting for the bus.
Busses are tricky at the Springs station it is the last on the route for pick up and drop off. Now if you are in a THV then you have to take a bus from the THV to SSR then another bus to the park of choice. Dont worry about the busses they are very frequent. I can say that the worst leg is DTD, but you can always walk there from Congress Park. The DTD busses often stop at a Water Park as well before returning to the resort. enjoy the trip and dont worry about the busses.
