There are three monorail loops.
The Resorts loop starts at TTC, then goes to Polynesian, Grand Floridian, Magic Kingdom, Contemporay, and back to TTC.
The Express loop starts at TTC, then goes direct to Magic Kingdom, and back to TTC, with no other stops.
The Epcot loop starts at TTC, then goes to Epcot, then back to TTC, with no other stops.
