As always, best to take a long hard look at the club/instructors and see if it's for you.
Remember, Cabair instructors are hour building. Sure, that's the case in other clubs, but I suspect more so at Cabair. Furthermore, I understand from friends who have been there, that it's not the happiest company to work for.
For myself, I could never see the point in paying their prices. There are a lot better and cheaper clubs around. I'd give them a miss personaly.
