While it's a stupid change, the pier is still a pier. Much like Cars Land is route 66. People suspect that they'll change the Soarin' film back one day. Marvel land hasn't happened yet. My point is, the park still has a loose California theme all around, and retaining a loose theme is better than just throwing in the towel.
But in the case of the latter, there can't possibly be a more fitting name than California Adventure. What would they rename it? Six Flags Over Texas never changed it's name. Now Texas is simply the location of the park, not the theme. DCA looks to be going down the same hole. It's becoming a high-quality amusement park.
The only way I see it changing again is if some CEO wants to place his own name on the dedication plaque, like Iger did with DCA, and I can imagine he might have the audacity to do with DHS.
Lol. Forget about one visit to Epcot Center as a child... Peter Quill lives in California!!
