First of all, I agree with the fact that WDW hasn't done enough to get vistitors back compared with the major expansions going on at both UO and SWF. Plus, it is much better to build during the recession times...the cost of labor, etc. can be much less, and you are ready to go once it is over. This is what I see happening at all of the non-Disney parks. Once people are traveling, look at the host of new things to do at UO and SWF!
However...I must also play the other side and say that Mission:Space is NOT just another simulator ride. I was fortunate enough a few years ago to work load and unload tests for this ride (a mock up of 1/4 of the building was set up, and we used lots of cast members walking in circles to see if it was possible to get the whole thing loaded in time, etc. VERY interesting) ANYWAY, we were treated to a glimpse of what will be the final version...and let me tell you that it should be wonderful. Is it enough to save Epcot? Well, no one attraction can do that. Disney is going to have to realize that they have to spend the money to "fix" what has been ignored for so long.
As for Primeval Whirl, while I do not thing that an off the shelf Reverchon Spinning Crazy Mouse coaster has a place in a Disney park (I have the catalog if you want to buy one for yourself however) but it is definately not a "kiddie coaster". A few trips on it should let you know that it can be quite intense if you get the balancing of weight just right. Would I rather have the original concept of the "Excavator" wooden coaster back there? DEFINATELY!! It would have worked very well there. But in reality, I also know that a wooden coaster is very maintenance intensive and in the current era of Disney cutting costs on everything, I am scared of how they could have ruined a great ride. But who knows? Maybe the Excavator will still see the light of day years down the road.
In the meantime, lets hope that next months announcement of the new ride at DAK brings some light to what are still some of my favorite parks. And maybe the pain it is to see them in their current state will go away too....
Here's hoping.
