Do you mean in terms of the actual animation or just the different setups? Neverland just shows different portions of the world in different games: Hook's ship and London in KH1, Skull Rock in Days, and the actual island of Neverland in BbS. All of them are in the same world, but they're just different areas. When we do go to Skull Rock in BbS, it's pretty similar in animation to the Days version, though. Atlantica... Well, in KH2, that world served a completely different purpose. We're not exploring it like we did in the first game, so there was really no reason for it to be bigger than it was. We see more in the cutscenes and musical numbers, but those parts of the world are just adding to what we already know is there from the first game. In terms of animation, I thought it looked exactly the same.
