There's "inform" and there's "complain".
Keep in mind that probably nobody is getting paid anything for the time and effort they put into putting on the ride. By the way that you asked the question you sound like an "inform" kind of person to me.
If you verbally abuse whomever you talk to, they probably won't want to put themself into that position next year so you'll get somebody new without the experience and your message will have been lost.
