MK in particular just feels so suffocating to me. The pathways are tight + it's the most attended park in the world = pain (I like big crowds because of what lack thereof means, but none of the other parks in the area have so consistently given such a feeling of being herded like cattle). It always feels orders of magnitude hotter than the others (I know this is how many feel about DAK, of course). It's also the most inconvenient to get to and from, bar none. The food is also...lacking, and the tap water there tastes especially sulfuric. On top of that, it's where WDW's lack of any thrill coaster is most glaring (even if one would fit better in the other three, it's still where I'm most reminded of it if that makes sense).
