I like how DLR is small. Disney World (which I think Everyone should Experience) Is like a City its huge you never have to leave. Disneyland I love how everything is walking distance. 3 hotels, Downtown Disney, 2 themeparks all within like a 1/3 mile walk. Disneyland is better then Magic Kingdom and the parks them self are up kept much better at Disneyland...
but in the end Disney World is a world and there is more to do, and it gives you the TRUE Disney magic as your transported to a strictly Disney "World".
