Make something together
Sandy Feet's lessons teach building and carving techniques with equipment provided. Rather than arriving with a picture that everyone must reproduce, ask for a lesson that suits the ages and experience in your group.
Agree on the details first
Confirm the number of participants covered, the final price, the lesson length, and the exact meeting point in your booking. Different pages on the operator's sites describe different group counts and beach accesses, so use your instructor's confirmation rather than an old saved address.
Bring the sun protection, drinking water and clothes you would use for time on the beach. Leave room afterward for anyone who wants to keep building, but do not make an outdoor lesson your only bad-weather plan.
