SSR shares buses with THV. THV takes a bus to the Springs stop and boards the bus there. THV also exits at the Springs stop.
For DTD, you can take the water taxi at the boat dock by the Turf Club over to Marketplace or you can walk. There is also a DTD bus. They need one because the water taxis stop running at 11:00 and DTD is open until 1:00 am.
