Has anyone done the zipline excursion before with wacky rollers? Was it as much fun as it sounds?

We have done the zipline last year I think in St Lucia, not at this port it was great and lots of fun.  This year we are doing it again, in Antigua.

I did the zipline last year in Antigua.  It was fun, but not what you expect.  There were 9 lines over a dry bed creek.  The longest line was 300 ft.  There big attraction was the challenge course at the end.  Most people didn't do it cause it is all upper body strenght and everyone was to exhausted with the climbing from line to line.  The tour was not worth the cost for what you got.
