We spend most days at Disney but make time for the others as well, we go for 14 days so find time to fit the other parks in.

In some ways rather than being in competition I see them as complimenting each other. They are able to offer different things. People are unlikely to choose Universal over Disney and generally if they want to see both they will just book enough time to see both. Therefore i don't consider it cheating as it isn't a zero sum game between the two.

My favourite is easily Disney. I appreciate the chance to go to the others for their thrill rides which I'm very impressed with but Disney manage to create this magical atmsphere that can't be matched by the others. Previously we've allowed a day each for Universal Studios, Islands of Adventure, Sea World and Busch Gardens while spending most of the rest of our time in the various Disney parks.
