I would recomend getting to the ride at least 30 min before opening. Probably even sooner because of where you are working. Because I haven't worked a coaster, I would guess that you would be getting the trains ready, cleaning the station, sweeping the qeus, and doing test runs. When they test run, there is at least one test run where the ride ops ride along to help test it.
I am not sure what happens on a coaster for closing. But I do know that the lines will not close early. All the lines close at closing time and no sooner. They then let everyone who is still in line ride. This might mean that you would have to stay at the ride for an hour, mabey more before everyone in the ques gets on. After that, they just clean up, put the trains in there storage areas, and then shut down for the night. I'm pretty sure thats all there is.
