As much as I hate characters taking over some attractions at Epcot I can say that Grand Fiesta is pretty much just an overlay on top of El royal di tempo. To my surprise, most if not all the scenery is in tact and the cultural aspect is still in place. There's some modifications and all new projections but besides that I can still catch a good dose of nalstalgia. And I'm not going to lie I do like that new ending scene they just added.
