It is indeed about 45 minutes on average. Granted you can cut that short if you are staying on the side next to the TTC and walk over, but to take the resort monorail to the TTC and then transfer to the Epcot line is about 45 minutes from door to door.45 minute by monorail to Epcot? Not by a long shot.
