Yes but, it's much much bigger, and has differences, both have HMs but are different, both have pirates but both are different etc.
They really aren't that much different. There are many attractions shared between DL and WDW, Small World, Big Thunder Mountain, Splash Mtn, etc. There were also similar rides that have been lost to one or the other park over the years; the submarines, Country Bear, to name a couple. It doesn't bother me at all if the same or similar rides are shared between the parks.
They say that DL guests are mainly local, so really, what difference does it make. I am not really a fan of DL even though it is much closer to me, too claustrophobic for me. My preference would be to have similar rides in both parks; I don't think it would hurt the attendance at either park since they are supposedly targeted at different markets.
