There is a regular sign up week with Swim School and I'm not sure when the next one is. I need to pop in and ask. You need to be fairly on the case and go in and queue up that Mon morning to be sure of a spot, but once you're in a class you get priority booking for the next term, so that's a one-off hassle. You go in with little ones under three and then I think older than that, they go in themselves. Can anyone else confirm? Anyway, go for it. At ?60 for 10 lessons, it's brilliant.
