I grew up going to the World. But after my first visit to DL, I was forever spoiled by it's heavier amount of offerings.
Since going to DL, every time I visit MK in Fla, I always miss the Pinocchio & Alice dark rides in FL, the much longer & more immersive POTC, with the bayou scene & extended caverns, Matterhorn bobsleds, Roger Rabbit Car Toon Spin, Mr. Toad, "hidden" Disney characters inside IASW, Storybookland canal, just to name a few.
MK in Fla never felt lacking until my first DL experience (imo). Granted, it has the more impressive castle, but for me being a ride junkie, visiting DL was (and probably still is) the pinnacle in comparison.
