WDW also has two sizes at their parks. The large locker should fit pretty much any tripod I've seen - they are big enough for a tripod, camera bag, bag of clothes, and a small cooler. Rumor is that Animal Kingdom's lockers are a tad smaller than all the other parks - though I've not used them. I have used MK and Epcot's lockers though. The small lockers will fit MOST tripods, though often you will have to put it in diagonally and angled up to down...the largest of tripods, or normal tripods with grip heads and such may not fit. The large lockers should be OK for anything, though if you have a large tripod with a pistol-grip ball head, you might have to take the grip head off.
