I don't buy or sign up for anything without researching, reading reviews or recommendations. Blue Blouy was recommended by a few parents and so far, we've been happy with the results. Everywhere we go swimming, people admire on how well our 3 1/2 year old swims. The pools are warm all year round and their staff are very friendly. We've researched other swim schools in the area, private instructors, etc., but Blue Bouy is worth every penny we have spent on our boys.
