I'm passing through LAS for a few overnight hours (late night incoming flight, early morning outgoing flight) and thought I'd spend them hopping from casino to casino.

But I don't want to carry around my carry-on backpack, with my laptop and work stuff. Are there lockers in the airport, or some other system to just keep my backpack at the airport? Any suggestions? (I don't want to check my backpack because of the laptop.)

Thanks.
