FYI - I didn't look closely at the signs, but I think the rates were $2/hour for a standard size and $3/hour for a much larger locker. It looked like there were only a couple large ones available, though, and their lights were out, presumably indicating that they were in demand and rented.

There are lockers in the secure area ... which is perfect.
