After reading this whole thread I still have the same feeling that I did when I first read the post heading.
People will book there vacation for Disney. I don't know how many people would book a whole vacation around Universal. Ye some people visit for a couple of days during their Disney trip, but this is no different then going to SeaWorld,
LEGOLAND or any other side place.
That is why I don't see Disney being screwed. You can compare rides and shows till the cows come home, but how many of you or your friends say I am going to Florida for a week at Universal.
Disney has built something that you can spend a week or two at and still not experience everything. From rides to shows to parades and fireworks and all the side experiences you can have both at the parks, but at all the resorts and DD and BW.
Further to that, I haven't seen too many travel agents in my area promoting complete packages for Universal.
That's all I got.
