It is about a 10 minute walk from MK to CR. It is the first stop on the MK Resort monorail whening leaving MK. This usually takes about as much time as walking.
If you are going back to MK after your dinner, I recommend walking (unless your feet are too tired.) The monorail stops the Poly, TTC, & GF before pulling into MK. Much quicker to walk to MK than make all of these stops.
