Hi Debbie,
Yes, it is worth the money and lots of fun and work if you want to do that part. I have heard that it can make some people sea sick, you are in an actual race against another boat. I didn't have any problem, I also was a main grinder, so that was some work, but well worth it, we won! These excursions do fill up quickly, so be sure to book it as soon as your can.
