Update: The property I'm at this week does not have One-Click internet. Apparently they have no authentication... you just connect to the ResidenceInn-GUEST network and you're good to go. I'm not sure if I've seen a Marriott property like that before, but no complaints here

. I'll update my One-Click saga when I'm back in the Courtyard next week.
In my experience, if I can't tell who is running the internet management at the property (not the actual ISP which may be Verizon or another huge telco), I look for a card on the desk for internet info or in the hotel booklet in the room. They
usually contain the name of the internet management company.
Most of the properties I've been at are now on Ethostream. There are properties that use Ethostream that don't have enhanced speed internet (a handful of CY and RI properties I've been to), but the one-click internet has worked at them welcoming me back by name with a connect button. Even when the button is just "connect", when I've been redirected to the property page I've usually seen
CONNECTED ENHANCED SPEEDin a grey box on the left side about halfway down the page, like the Springhill Suites property I was at this week.
