How much can I do at Disney world (from this list) in two days?

You may want to pick two parks you want to see the most and do those. The Magic Kingdom is a must and has the most to do...I'm 25 and still love the Magic Kingdom. Being able to have time to do everything depends on how busy the parks are. I went in December for only three days and if it hadn't been for the extra magic hours resort guests benefit from, we wouldn't have been able to do much of anything. We didn't even have time to go to the Animal Kingdom and spent all day at Epcot and only rode Soarin' and Test Track....so if you have to knock something out skip Epcot and try the Magic Kingdom and Hollywood Studios or the Animal Kingdom.
