My husband and 16 year old daughter did SUP while my 14 year old daughter had a surfing lesson (and I sat on the beach). I'm happy my 16 year old paddle boarded before on lakes as their guide just took off once they got on the ocean. Even on the beach he didn't seem like he wanted to be there. They headed along the shore to Black Rock and then turned around. On the way back they said the guide was way ahead and he never looked back to see where the rest of his group was (he had a young girl riding tandem with him and he seemed annoyed by that). If someone in the group was struggling, he would have never known.
My 14 year old surfing didn't have it much better. It was a bit disorganized at the beach and my daughter was put with a larger group as they were waiting for someone to show up. When they got in the water it took forever for a guide to realize my daughter was there to help her catch a wave. Once she connected with a guide it was much better and she did have fun. If she wanted to surf again I would use a different tour.
