I have a problem even carrying a camera at Ditneeland. I always end up as the one having to hold on to the camera so on a few rides I spend more time focusing on not losing the camera and less on enjoying the ride.
It has been a couple decades since my last visit to Disneyland so I don't know, do they finally offer temp storage lockers? I would swear as a kid I remember they had them and then the lockers went away. I would love to have them in close relation to the rides where they matter. Then again I doubt I would stuff a few grand of lense and camera into a quarter per ride locker rental. Life was simpler when I just rode the rides...
