It's a nice attraction. I didn't have time to properly book a tour, but as far as I could tell they weren't prepared to cater for English-only speakers. I just followed when people told me to line up and exited in the directions the told me to and enjoyed the structures and the artwork for what it is. Due to the pollution it's hard to see off into the horizon but you can get a really good view of the layout of the surrounding city. The show motion cinema/projector show / ride on the way down was pretty cool. You got the views as they would have been in ancient times with a Chinese narrated animated projector show all around you as you sat and slowly revolved around the tower.
