So make sure u are arriving on time and it only takes about 30 min for the edge walk experience. If u are not wearing a running shoes with shoe lace, they will provide you one. They will get u suit up and put on your harness, my harness was a bit too tight. The instructor was very encouraging and always asked us how we felt. They always tried to do some small talk when they are trying to put and test your harness. It is perfectly safe and don't worry u will not fall. There are 2 safety rope and an annoying 'seat beat' hanging behind your back! My husband bought it for $130 each ticket last year for my bday and i believe it cost $195 this year . It also include access to skydome . It was quite busy today because blue jays game has just ended. Oh yeah, we heard the horn that blue jays won and we were cheering them from all the way 356 metres up. It was a beautiful view and nice weather for edge walk. They allow u to wear your sunglasses but they will put a landyard on the back so it won't fall. If u are afraid of heights , u will be able to overcome your fear after this.
