Which of the Disney World parks would you leave out?

As you may find by looking at some of my other posts, my g/f and I are going to Orlando in May. As far as Disney is concerned, our original plan was to visit 3 of the parks (Animal Kingdom, Magic Kingdom, and Epcot.. leaving out Hollywood Studios). We’re considering the idea of skipping one of the remaining 3 parks, but aren’t sure which we’d rather drop. I’ve been to Disneyworld a few times before, but the last one was almost a decade ago now. As such I’ve visited the Magic Kingdom, Epcot, and Hollywood Studios (or MGM as it was called at the time), but it’s been a long time. Also I’ve never been to the Animal Kingdom. Any comparisons or contrasts, personal opinions, experiences, what have you, would be appreciated.

Things to keep in mind:
-IF we end up still going to all 3 parks, we’ll be spending a whole day at one, and splitting a day between the other two.
-Seaworld Orlando is high on our to-do list, but we’re debating the idea of picking between Seaworld and the Animal Kingdom, as there would be a fair amount of overlap in “attractions”, and my g/f is far more interested in the aquatic end (whereas I’m spoiled by living in a city with one of the best Zoo’s in the world).
-We live near Cedar Point, so NONE of these parks will come close on the thrill aspect as far as rides go.

If you have any other suggestions for things to do in Orlando, feel free to leave those as well… THANKS!
