I haven't been to US or IOA for about 3 years. I remember that next to some of the more "intense" rides, there were free lockers to store your stuff (free for like 1 or 2 hours, I think). Do those still exist? Are they still free for that short amount of time? If they do exist, what rides are they next to now? I'm debating taking my DSLR camera, but I'll skip it if it's going to be a major hassle to store.
