Lockers- available or sold out?

[Disney.fan]

We've never rented a locker before but would like to for our upcoming trip (mid October) for each one of the parks. I am wondering if they are usually always available or if they are sometimes sold out? Thanks!!

I have never heard of them selling out.

We always rent a locker and have never seen them sold out, even during busy spring break. I've also never seen anyone in the locker rooms when we're there, except when it's raining. lol
