Thanks for the quick responses, guys.
I contacted the park, and the lockers near the main entrance and Oktoberfest are all-day lockers. I really wish I could bring a smaller camera, but I am a typical "poor college student" after all, and don't have the extra money to buy a camera for the day. Besides, the pictures I hope to bring back from this should more than make up for the money spent on a locker.
I just wanted to throw something out there since I saw a few comments on it. Just because the ride hosts don't watch the bins doesn't make them unsafe, necessarily. In my three years working for Cedar Fair, not once have I ever had an issue where a guest lost something from a bin, and I've worked or been in charge of major rides such as Maverick, Shivering Timbers, maXair, and Thunderhawk. Most of the time people are in too big of a rush when they get off the ride to steal someone elses things from a bin. Better to put your stuff in the bin than to try and hide it and take it on the ride.
Again, thanks for the responses, and maybe I'll see some of you a week from Saturday!
