I will be heading to Toronto in a couple of weeks and we are planning a day at CW. The fast lane passes sound like a must have for mid summer so, despite the cost, I will be getting them for my family of 4. My question is, if we are getting the fast lane passes anyway, does it matter which day of the week we go? Will the fast lane passes be just as quick on a very busy day as they are on a not so busy day?
