Wacky rollers kayaking and river tubing

Has anyone ever done either of these trips with Wacky Rollers? I'm not a strong swimmer at all and am worried about the kayak tipping over. Also the website mentions mild Rapids for both kayaking and tubing, wondering how mild these actually are? Any information will be gratefully received.

Anyone? I am also interested.

I realize this is a super old thread so you might not be looking for this info any longer...

FYI - the river tubing and kayaking are both highly dependent on the weather. We've tried to do both activities twice on cruises and they've both been cancelled due to weather - we were also told that the kayaking is cancelled often because of infrastructure damage from their big Tropical Storm two years ago.

We ended up doing a fun tour with Wacky Rollers last week when tubing was cancelled - we were disappointed, but it was a fun alternative.

They're a great company with good guides. Dominica is a beautiful island!
