Yes we did.
We looked at three different ones, two in catchment and one out of catchment. Basically if you call the school they will tell you when their days are when you can visit. I can't remember exactly but i think they do the visits around the end of Sept and Oct.
Its definitely worth doing.
Also - you will need to put down your catchment school somewhere in your list of three but not necessary first.
One thing to watch for - if you decide to put down a school that is out of catchment and you get your child in, when they go from infant to junior you WILL have to reapply and you probably wouldn't get your child into the junior part even though they have been going to the infants
