Disneyland works a bit differently than WDW does when it comes to announcing special events. Because DL usually puts out their park hours about 60-30 days in advance, they usually do the same with their special events. It seems they plan on having a “Spring Fling” but the 2014 dates have not yet been announced. I would keep an eye out on the Disneyland Events page, and the Parks blogs for announcements as we are getting close to when that info should be released.
