Okay, I note that this is your first trip to WDW, so I thought I would add this: since you want to take the monorail, when you exit the MK, head to your right up to the monorail platform. There are two monorail tracks and they are clearly marked. Like ncgolfer said, don't take the line to the TCC, but take the resort line. Since you plan to do this on 3/22, note that this week will be relatively crazy at WDW due to Spring Breaks across the country, and because that week leads into Easter. Despite that, you should not encounter huge crowds for the resort monorail leaving the MK shortly before 11:00 am. The monorail circles the GF, Poly and CR quite quickly and regularily. If you exit the MK 15 min before you want to arrive at CR, you should be fine. BTW, if you decide to walk, head left when you exit the MK and follow the walking path to the CR.
