Yes, but while rides are important they are only part of DLR. Did you see a fireworks show? Fantasmic? Parades? Disney Electrical Parade at DCA? DEP is gone now but we have World of Color. And then what about Billy Hill and the Hillbillies and other smaller shows? Did you stop to see any characters? Did you take any kids to Jedi Training Academy (and have to see the show multiple times waiting for your kid to get chosen)? Princess Fantasy Faire? Pixie Hollow? Did you wait in line to see any princesses? Winnie the Pooh? Did you visit DTD? How many restaurants did you eat at? Any character meals?
If one wants to see fireworks, Fantasmic and World of Color that will take three days there. Just for the major shows. Yes, it is possible to do fireworks and Fantasmic on the same night. Depends on size of the group and whether you have any kids that can stay up that late.
Bottom line IMO is that three days is the absolute minimum to visit DLR and four days is better. But you will not see it all. If you are the type that comes lates each day, does not use Magic Mornings effectively, does not know how to use FP, etc., etc., then five or more days would be a good idea.
