Are there lockers for rent at the top of the Stratosphere Tower (Vegas)?

Maybe it’s GQ, but it’s about entertainment, too…

I’m in Vegas now, and want to go up to the Stratosphere tower to take some pictures and ride the thrill rides. I’m concerned that there won’t be a safe place to stow my camera when I’m on the rides, however. I imagine it’s likely they’ll have lockers available because this has to be a common occurrence, but I’d like someone to confirm this.

So…can someone say for sure one way or the other?
