Hi were going on a 8th grade field trip to universal and i was woundering how much would a locker cost

Lockers usually cost from around 2 to 4 dollars

I'm not sure what it cost.

They are free for high speed rides. However must consider that for water rides isn't for free and your stuff might get wet so be prepared

Used for free

It's free at each ride for like 45 minutes

Lockers are located at each Rollercoaster... and free for about 30-45 minutes depending on the wait time for the ride. I'm not sure what it costs to have a locker for longer durations.
