What a fun experience! Our family of 6 adults (4 young adults and 2 "mature" adults) booked this about a week before our visit to South Padre. The night before our scheduled lesson, one person from our party was delayed due to a flight cancellation. We contacted the owner and she happily rescheduled us for a later time so that everyone could attend. We met our instructor (sorry I didn't catch his name) at beach access #16. He brought the tools. We were amazed at what we learned. I've been making (bad/sad) sand castles for so many years. Now, our whole family has the skills to make beautiful castles! It was interesting to learn how to build a solid base, and then the fun part for me was "decorating" - adding steps, windows and doors. One and a half hours was a good amount of time for the lesson. After the lesson, we went back to "our" beach and made several more amazing castles. Our instructor was friendly and informative, right on time, and very knowledgeable. I'd definitely recommend this lesson, and my family is excited to take the advanced lesson the next time we are in South Padre.
