When is your trip? If it is on a weekend or a day when the park is open to midnight you should be able to fit in a lot from both parks (as others mentioned, they are about 100 yards apart). I don't know if you can do EVERYTHING but you should be able to get a lot in, particularly if your main goal is to do stuff not in MK (though you should do Pirates, the DL version is about twice as long as the MK version and is a better ride). One thing I would consider skipping unless you REALLY want to do it is Mickey's Fun Wheel, it is a very slow loader and the wait is really long (at least it has been every time I have ridden it). If you are only doing one day you could maximize your time better without that wait.
The thing with WOC is there isn't as much good and bad sections as there are good and bad locations within each section. If you can get close to the front of a section near a rail that can help avoid getting blocked out by other peoples heads (everyone stands for WOC). Make sure you get there early enough for the pre-show, it is a pretty fun warm up.
