Since ME is basically Mears, I would guess that the typical Mears times would apply. In December, it took me about 2 hours from the time my plane landed till I was in line at Pop Century
-25 minutes to get off the plane and ride the tram to the main terminal
-30 minutes to get my luggage off the belt
-20 minutes waiting for the rediculously overcrowded van to show up
-35 minutes travel time to the WDW area
-25 minutes as the van made stops at 3 or 4 other resorts before Pop Century
Of course, if you happen to be getting off at the FIRST stop the van makes, that will shave 25 minutes off your travel time.
