We went on the beginner/group lessons as a family of four (11 & 14 year olds) in August 2021 over two days as we had such a good time the first day we booked again for the day after.
All the instructors were really friendly, enthusiastic and helpful, you can tell they are passionate about what they do, I doubt any of us would have made it to standing up if we hadn't had such good and clear instructions. They spent alot of time helping everybody out in the water and were particularly good with all the younger children that were in the groups, which is particularly important if you're a parent taking kids along, Rhiannon was great with our 2 boys. The wetsuits, boots etc. kept them super warm too.
All in all it was a great experience which we all enjoyed and definitely a good workout too. If you are up their way then I'd definitely recommend you give it a try, so glad we did, such a great feeling when you catch a wave and finally manage to stand up!!
Would love to go back and do it again. It was a great part of our entire trip but even if that was the only thing we'd done it would have been worth the 1000 mile round trip.
