This is how I do it...head to MK, then over to CR. Boat to WL, boat back to CR and monorail to the GF. Back to MK. Bus to the Epcot resorts....BW first then walk to S/D, YC/BC. Those are the biggies.
If you want, and have time, head to a park and then bus to AKL and Kidani. The moderates are also nice to see!
