Waterworld Swim School

The main disadvantage of this swim school is that it's only open for a part of the year - the times when the swim centre is open. So if you want your kids to keep learning during winter you either have to take them to a different swim school or just wait.
Having said that, their prices are very reasonable and class sizes are good, instructors are friendly and patient even with scared kids and there's lots of space for classes. There's also almost always spare lanes for parents to swim in while waiting for kids to finish &/or for kids to swim around before/after lessons.
I just wish they'd find somewhere else to be able to continue lessons outside of summer.
