I drive a
scooter, yes it only goes 35 mph, but I still can't imagine such a long ride! Wow!
At any rate, I have stayed at SSR 4 times already and I love it! I always stay in Congress Park because it has the most amazing view, it's very close to DTD and it seems quieter because of the theme pool being a bit of a jaunt.
That said, if you plan to use the main pool and it's hot tubs (there is one hot tub at Congress Park's quiet pool) you might want to stay closer, like the Springs, because it's just a short walk.
I'd also like to suggest that you try to spa. It's WONDERFUL! I had the most amazing spa experience there with the mystical forrest treatment. I highly recommend it!
The resort is quite laid back, very friendly and calm. It's a retreat unto itself and, although it can be filled to near capacity, you would hardly know it. The bus service has never been a problem, just don't expect to always have a seat leaving Epcot after Illuminations.
Good luck and happy riding!
