Our 3 year old is taking lessons here and he cried or whined the first few visits. The patience that the instructors here show is amazing - they know how to get the kids comfortable in the water and distracted with their own fears. The number of activities they do is good, considering the group lessons are only 30 minutes. The things they have in the pool for the kids is amazing - with floats that act like floating platforms so kids can sit on them, partially submerged stands, slides, it's pretty cool.
The cost is little more than we'd like and the location is terrible. It's just too far but we are scared that MAC won't be as good for a toddler. I wish they were either much more expensive so we'd stop going, or much closer so we didn't think twice about it!
