Being a ride op is a great experience, so long as you remember that it is like any other job in the respect that it has good and bad days. Yes, you have guests yell and scream at you about how they should be able to cut in line, get out of line then back in, have their too-short kid ride, take this-that-or the other thing on the ride, etc., you have to clean up vomit, work long hours, hear people complain about the ride/park even when you're working really hard, the weather can be nasty, and you hear the same stupid "am I tall enough" jokes so many times you want to start telling people no and not letting them ride (a hint -- they don't tend to like that response!). But you also get to see the absolute joy on the kids' faces when this is their *first* coaster ride, you see a lot smiles, hear the cheers for a good ride, meet a lot of happy people having a great time, and work a job that will have lots of people asking you "wow, what's that like?!" I highly recommend it! :)
You can also check out working coasters and working at amusement parks in general at my site below, if you want specifics about what it's like to work on a coaster crew.
