What is a key question to assess the customer's previous experience with the activities?

The question that best assesses the customer's previous experience with the activities is focused on whether they have engaged in kayaking or stand-up paddleboarding (SUP) before. This is crucial because it directly informs the guide about the participant's familiarity with the specific activities, allowing for a tailored experience based on their skill level and comfort. Knowing whether a customer has prior experience helps in determining the level of instruction needed, potential safety concerns, and the overall enjoyment of the activity.

In contrast, while asking about a life jacket, confidence, or swimming ability is relevant to safety, those questions do not directly address prior experience with kayaking or SUP. Therefore, they may not provide as much insight into how the customer will interact with the specific activities during the outing.
