First off, the prices to get to the top are a rip off and the time it takes to get in is ridiculous. However, it is a must if you've never been or plan on returning to Toronto. If you're going to spend the money to get to the observation deck, then you should spend the extra to go higher. I couldn't afford the wait time to go higher or I would've. I hate going to an observation deck and having to view through dirty glass. Plus, it was so over-crowded that I was miserable. The glass floor was neat but I've never seen so many people taking selfies in my life.
