I was going to name several that I thought were not generally adored (COP, Living with the Land, Dinosaur, People Mover), but then I read through all the replies and realized they are more loved than I thought! Basically, if I'm riding a WDW ride or enjoying a WDW attraction, it means I am at WDW so I am happy! One of my very favorite things that I don't see mentioned here (though I'm sure it isn't generally hated) is the small boat rides between the Poly/GF and MK. I love how relaxing and quaint they are even if it takes longer than hopping on the monorail.
