From what I have read the WDS version of the ToT is a copy of the one at DCA not WDW. In that it does not have the 5th dimension scene so you go straight into the lift shaft. Also it does not have random drop sequence like at WDW.
Now the ToT's I can't wait to try out on my Disney trips this year (I love the one at WDW), but if the cars ride is like the Teacups I'll have to pass on that. Give me a tall, fast, multiple looping rollercoaster and I'm at the front of the line to ride it, but teacups!! No way, the spinning makes me so sick!!
