All depends on what resorts you are at. If you are at one of the MK resorts (Poly, Contemporary, Grand Floridian) you can take a monorail. If at Poly you can also walk. As for some of the other resorts you can take a bus to MK and monorail to TTC.
From most resorts take the bus to Magic Kingdom or Epcot and then take the monorail.
Resort guests should rarely need to go to the TTC unless driving to the MK. Everything that is done there can be done at MK or Epcot among other places.
