Locker Question for MK, Epcot and AK

[VickiHD]

How quickly does the lockers sell out at MK, Epcot and AK ? (We're used to DL)
We plan on getting there during Early Entry and the "plan" is to get one right away. Do I have a chance or bring a larger backpack.
Thanks

Been using those lockers for years and have never had an issue with getting a locker. Maybe not the size I wanted, but I got a locker.
