This is what I get on my iPhone, latest IOS. The first page doesn't display properly. When I go to the search page, I have a lot of blank space. The campgrounds display, but it's a lot of scrolling up and down. Also, I liked the feature before when you searched for a campground, say in Foley, Alabama and it would show you other cities nearby. The iPhone won't do that. Also, the iPhone will throw up ads for other campgrounds that I'm not interested in. Like when I look at Magnolia Farms RV Park in Foley Alabama, I get this big ad for GatorTown RV Park. "Newest RV Park in Anahuac See Low Introductory Rates!" It's easy to accidently click that arrow while trying to scroll down.
It won't work at all on my work computer. Granted it has IE9 but that's company mandated. It works better on Chrome.
I do tech support for a living, so I'm well versed in blocking popups etc. An example I'd like to throw out there is Windows 8. Windows 7 was a perfectly good operating system. As with any Windows system, it has it's flaws, but Windows 8 is a complete cluster and Windows 10 is already on the horizon to fix what they mucked up with Windows 8.
At any rate, I love RVParkReviews.com, just don't like the "upgrade".
