Meh.
After waiting in line to purchase two general admission tickets (Total: $72.32 Canadian), we had to wait in another line, about a half hour, to take a 58 second elevator ride to the observation deck.
It was packed. People everywhere. You had to jockey for position to take any and every picture.
We stepped on to the glass floor with trepidation at first and after that it was ho hum.
Something to do while in Toronto, but for the price they charge, it is NOT a must do.
