It's pretty cool. The pay is significantly higher than what EMTs on a private ambulance get paid. Mostly hand out bandaids and such but every once in a while something big will happen. We've had an anaphylaxis, status seizure, and open tib/fib so far this year... those are just the ones I can think of right now.
Our service is cool because it's ALS and it pulls in people from all over. Really awesome being able to talk to people who work all over.... fire depts, ERs, privates, hospital-based, flights.... it's a great way to hear a wide range of experiences and definitely a great way to make connections.
A big thing is being able to comfortably decide if the person can just go on with their day or if they need an ambulance. That is usually pretty easy but sometimes it can get sticky, and it's definitely hard to operate in that gray area sometimes.
While not an amusement park I worked with several that worked in high end casinos in Vegas, It was a very fun and exciting job - as long as the work atmosphere made it that way. B ut something different and makes it fun. Work pay probably varies froma rea to area though.
