There are many differences between TDR and Disneyland Resort(DLR). DLR is much larger than TDL. Disneyland is twice thirds times as large as TDL. I think you can't enjoy all of Disneyland in 1 day. So you have to stay for several days to go around DLR. DLR is consisted of Disneyland and Disney California Adventure. Disneyland differ little from TDL, but there is a great difference between California Adventure and other Disneyparks. California Adventure has many genuine roller coasters and target on the older group than Disneyland and other Disneyparks.
