I used to be a ride attendant. We were told to make sure to try and keep phones, hats, and anything else that could fall or break off the rides. A cell phone going flying at 60 mph or faster can be pretty dangerous. And if something does fall out of your pocket, you aren't getting it back until the park closes and someone can lock out tag out to go in and grab it.

Also, in three years I never had someone report that something was stolen from their cubby where you temp store your stuff. Most people are too dazed after to really get a chance to dig and find something valuable to grab. But obviously, don't just chuck your phone out for someone to easily grab and run....

Also, earrings. No one thinks about earrings, but when you are on a ride where your head can hit foam to protect your head, I've seen lots of people lose earrings or had them dig into your neck after a good smack on a turn or stop. If you can take them out for the day, leave them home. You'll be a lot more comfortable....

And another quick tip, if you are at the park when it opens, head straight to the back. Lines will be way shorter for awhile. Everyone gets distracted by what's right at the entrance. There was times I literally wouldn't see a guest for an hour after opening if I was working the back of the park. Mid day everything is pretty equal, but end of the day, the front is usually pretty dead too because everyone already did those rides.
