Our third straight Walt Disney World park day was our Epcot day. After hitting The Magic Kingdom hard for two days in a row, Epcot was a nice change of pace. Because we planned to get the most out of each day, we opted not to do a park hopper, and just did two dedicated days to The Magic Kingdom and one to Epcot. Had we stayed longer, I would have loved to have added Hollywood Studios and Animal Kingdom - but for us, The Magic Kingdom and Epcot (and a four night stay) was perfect (there's always next time!).
I had read to allow 40 minutes to travel from The Contemporary Hotel to Epcot via the Monorail (there is a train change involved). Even first thing in the morning, I'd say this was pretty accurate (figure in security checks, waiting for trains, standing in line to enter the park). We left our room around 8AM, and were under the geodesic dome waiting for rope drop by 8:50AM.
