After a year swimming at dulwich dolphins in the regular swimming lessons I would like to give some feedback here. Whilst dulwich dolphins is excellent for club level swimming and some of the instructors for regular lessons are also good, my daughters lessons have been a real disappointment. Lessons are often not the full 30 minutes, they allow up to 12 children per level which is more than at other swim schools, teacher was unmotivated and often looking away and not teaching, teachers from different classes talk to each other during lessons, prices have increased to ?10 per lesson and now they have changed the set up so children are no longer swimming the length of the pool but only a third as they have in introduced extra classes at same time. My daughter has now moved to tiger sharks on a sunday. Instructors are motivated, give the children feedback and lessons are 1 hour in a 25 m pool. Having spoken to other parents who shared similar concerns and thought they were being fobbed off I think it's a shame that dulwich dolphins are letting themselves down with their swim school. I would still recommend for club level swimming though.
