They claim to have Enhanced Internet. The first week I was at the property (when I enrolled in One-Click) I connected to Enhanced Internet. I took out one of my test phones last night (that hadn't been registered for One-Click) and confirmed that it still gave me the option and allowed me to connect to Enhanced Internet (interestingly, this doesn't seem to have upgraded the connections on my One-Click devices). I'm connecting to COURTYARD-Guest.

However, I did notice there's an option to un-enroll my devices, but it's not obvious. After connecting via One-Click with a different test device, it redirects to the main page. On that page in the top left corner there's a dark blue hyperlink against a black background that says "Remove this device." I tried clicking on that last night and it said my device had been removed from One-Click... although I continued to get Wi-Fi on that device for the rest of last night. I'll be back at this property in two weeks, and I'll be at a different Marriott property next week, so I'll update once I try at the new property.

Thanks for your help Kenny!
