I'm a reluctant tourist trapee, however I feel my disinclined visit to 360 warrants a positive shout out. You don't just want to say you did the CN Tower. You're after experiences. The best view of the city and Lake Ontario, good service, and a prix fixe that's predictable at $55. When you'd pay 3/4 that amount for 1/3 of what I described it's the only way to do the CN Tower without feeling hoodwinked.
Tip1: Early reservation gets you a window seat and a less than full house. In my opinion, on a spring or fall day with the right company, and the sunset, it's a deal.
