We're at Disney right now, and it took us just over a day to do everything at DAK, and that was with fast passes for Pandora. I think it is a full day now if you are willing to do what is in the park. The challenge comes in when you have families that don't cover the age range that ours does. We cover from 6-16 and us and grandparents this time around. We did everything and enjoyed it. But most families won't do the little rides and the big rides because their family doesn't need it. Add the 3rd ride to Pandora, bring in an attraction or 2 in Africa that aren't tours of animals, bring in 2-3 attractions in Asia is what it really will take to make a full day park for everyone, regardless of age. Those attractions don't all need to be $250 million behemoth's either. I firmly believe every addition should A-ticket through E-ticket added before another E-ticket is added. There seems to be a huge fixation on E-ticket rides right now, and are leaving young families to sit in line for hours for their rides, and they are the ones you need to get into the shops and restaurants and out of the lines.
