I have noticed how much DCA has been improving over the years and came to realize that the same exact problem DCA is facing, is what Disneyland faced when it first opened. Disneyland was said to be horrible and had many problems that were not fixed at the time. But once Disneyland started to get new rides such as the Matterhorn, Subs, Mansion, and POTC, it improved drastically. I bet the same will happen for DCA. I mean look at it this way. People first made fun of the park, but now they are looking foward to the ne Monsters Inc. Ride. You also have the roller coaster and Tower of Terror that are pretty good rides. Of course there is also the Muppets and Soarin, and Soarin is a huge success from what i have heard among the public. Sure DCA struggled in the beginning just like disneyland. But I say Give-or-take a few more years and rides, it will gain more popularity.
That is my 2 cents.
