The R1 goes to many places, depending on which R1 you take. We take the R1 to the ferries in Puerto Morales all the time (which are the very last 2 stops on that line before the bus turns back around) and there's no stretch of that trip that's dangerous. In addition, I've yet to hear of a single sober soul that's taken the R1 that goes down Avenue Lopez Perillo (I assume that's the cruceros you're referring to) that's been accosted while minding their own business. Yes, there are bars on the doors and windows there, but that is not a differentiator of good and bad neigborhoods in Cancun. And yes, if you carelessly leave something lying about it will dissapear - forever and faster than the blink of an eye. And yes, if you get in someone's face there, you stand to lose the argument in a highly definative manner. But all of that is as it should be. The residents of Cancun, however, are neither agressive nor predatory towards visitors (Yankee tourists included) that treat themselves and others with respect - the culture simply does not support that. Now - if you're prone to being stupid - and we know that there are those that can and do act stupid even (and perhaps especially) when they're sober - then Lopez Perillo is not where you should be dawdling about. The one thing I will agree with you is that there is nothing there for tourists - but as has been said so many times in this post, it's easy to get there by mistake. And as I said previously, I don't recall ever hearing of anyone that's been harmed in any way for simply making that mistake.
