I agree with what the others said in answer to your questions. Also, WALKING to MK was actually quicker and easier than taking the monorail. We also chose to walk back, though it would have taken about the same time to take the monorail (the monorail loops, MK, then CR, then Poly, TTC, Grand Floridian, then MK again, so if you get on at CR you have to do all the other stops before MK, but if you get on at MK CR is the first stop)
It was so nice to just walk on over to MK, and walk on back! Loved it!
Enjoy
