Usability 
Part of the Wyndham Hotels Group, Days Inn is an international chain of budget motels. This site lets you search for and book rooms at Days Inns in the US and Canada and manage existing reservations.
It's easy to find available rooms and there is considerable information about the amenities of each property and individual rooms. Booking using a phone keypad is quite difficult because Wyndham requires completing a form with 12 required fields. Fortunately there is a click to call number for each hotel so you can always book with aphone call. You need to use a smartphone or Opera Mini to access this site thanks to some very large pages, up to 250 KB. Most feature phones can only handle pages under 20 to 50 KB.
