I agree that Disneyland is the best single park in the U.S. It has a very different feel from WDW and from the MK in particular. The downside is that it is smaller and therefore you feel the congestion much quicker than at WDW. You must ride Pirates of the Caribbean at DL if you like it at WDW--it is a much longer and much more impressive ride at DL. Fantasmic is also a much different experience at DL.
