Objective Behind Kayaking

So, now there was a reason behind kayaking, previously, Paul was doing it just to have fun like other tourists now he was excited about meeting the great whales family. However, that idea itself is scary, the whales are not man-eaters but they’re too big for humans. Yes, whales won’t harm you intentionally but their huge size and numbers may bring you into trouble. Was it safe for Paul to think on tour guide’s advice seriously?
