Also keep in mind that the TTC (which is the parking lot for MK as well as the junction of all 3 monorail lines) is next door to the Poly, and is an easy 5-10 minute walk along a pathway between the two places. So you can get on the express monorails from either MK or EPCOT, get off at the TTC and simply walk to the Poly. The Our Laughing Place wizard doesn't mention that option.
