Nope, not 50-cents per entry. Empty lockers are unlocked and have a little orange key with a black strap stuck in. You put your stuff in the locker, put in the two quarters, close the door, then turn the key to the right and pull it out. When you want to get back into the locker, you just use the key to open it up. It'll cost another 50-cents if you want to lock the locker again.
Yes, the cubbies were present at all the rides (well, can't say whether the Plunge did, 'cause it was closed when we were in that area).
I kinda like the cubbie system they have at, I believe, Patriot. Where it's a double-sized cubbie with a plastic door that the employees slide to cover the items of the people who are currently on the ride. Keeps people from grabbing other people's stuff when more than one train is being used.
