You'll work hard and get paid well (IMHO). They check the RV parks they put you up in, and if you have issues with the park you can usually use Amazon as a channel to get things addressed if necessary.
Amazon has their way of doing things. Try not to re-invent their wheel while you're there. I always tell myself this, and usually end up ranting about issues to management while I'm there anyway, just can't help myself.
Some folks have reported getting "nagged" about getting their productivity numbers up to Amazon's targets. We've never been approached about this, so we haven't had an issue. They do post everyone's figures daily so you can see where you stand, I say don't worry about the numbers unless a management type asks you. Sometimes an "assistant" will tour around checking with folks whose numbers are below par, they're supposed to be there to help you improve, so don't take that as a "telling off" because it's not.
We're going again this year for our 5th season, if that tells you anything.
