If you’re staying in a DVC Poly room, those buildings are super close to TTC. It’s like a 3 to 5 minute walk to catch EP monorail. That monorail ride is about 15 minutes, then 15 minutes back. We love riding around through EPCOT!
The Poly resort monorail is different and I find that to have alot more hiccups, pauses, delays. The EP monorail usually is more reliable in that sense. They keep coming like every 10 minutes then straight shot to EP. The MK resort monorail is hit or miss - the past few years we have a 50% rate of them taking 45-60 minutes from point A to point B, including going to VGF from MK and another time VGF to Poly, both were one stop away. We try to take the resort boats or TTC ferry to get around MK area, or walk.
