I have been on Pirates many dozens of times, and it is one of my all time favorites.
I can't believe I never noticed the differences between the Disneyland and MK versions. It had been so long since DL for me when I went on the MK version, I did notice it wasn't exactly the same, but didn't realize how different it is. Apparently, it is much shorter (reports vary, but some said half as long) and only has one flume versus three (one report said two, but I remember it having three...don't know if that's changed).
Anyone been on both close enough together to compare the two?
