Well, you can always read the original stories of Sindbad, to give you a gist of what is happening. The spoken parts don't provide any deeper insight to the ride...except perhaps with the used boat salesman at the end.
I think someone could make a killing providing translations to the rides in TDR. It's not hard to enjoy a ride without a translation, but understanding what happens when so many rides are story-driven gives you a larger sense of appreciation.
Maybe I'll have a pokearound on the 'net and place a copy for reference. Wish me luck
