I agree that Universal has grown more popular, but I don't think Disney has necessarily rested on its laurels recently. While I disagree with the choice to not add a fifth gate, Disney has recently built New Fantasyland, is about to finish Pandora, and will be done with Toy Story Land and Star Wars Experience in the next two years. Their popularity would have increased drastically if they had started these projects at the same time, but obviously they didn't have the money to do multiple jobs of this scale at the same time. So although Disney hasn't expanded the number of parks, they still have a lot of stuff in the works that I believe will re-elevate its position as the best family park in Florida and Eastern USA
