I didn't see the wave runners listed either, however when we were there in May they did have them parked on the beach and I did see people go out as a group in them with a CM leading the way out to sea. I think they were gone about 25 to 30 minutes, then returned. It may be part of the eco tour, but I havnt seen it, just know they do exist there. I'm going again in December, I'll post what I find out while I'm there. I will ask at the excursion desk on board. They know everything about things to do on CC.
