I took the "Original Sea Caves and Kayak tour" with Becca and Marcus. And while they were cool guides with interesting stories, it wasn't really worth it not being able to actually go inside the caves. It wasn't their fault, it was due to high swells making them unsafe. But we essentially paddled out, I got a little sea sick, we listened to the history of caves, and we paddled back in. If the "Sea Caves" half of your tour is the most interesting part, then perhaps cancel the tour. Other than that it was more of a "how to kayak" for people who'd never done so before.
