You have to board a bus and then you get dropped off at the Springs bus stop at SSR. You then have to wait for the next bus to show up to go to your destination. The Springs is the last stop for the busses to make before they leave for the parks. SSR is the largest DVC resort and sometimes the buses are full and no one can get on at the Springs stop. If you are near the Grandstand section you could walk from the Treehouse Villas to that bus stop. That stop is the first one for pickup and drop off. If you have a car you could just drive over to a bus stop too. Many complain that the Treehouses have poor bus transportation. There is a landing to board a boat to go to Disney Springs at the Treehouses.
