I have to disagree on them not raiding the week exchanges. I've been checking for Vegas, and have never had a problem trading into a week at Wyndham/Worldmark Tropicana for many years. Wyndham has now reduced almost all of their week exchanges to 5 nights, Sunday to Thursday, and some for just 3 nights. No Fri or Sat nights are available anywhere in Vegas for week owners at Wyndham properties. I'm sure the Fri and Sat are available for point owners to book into, for the increased weekend required points. These only apply to actual Wyndham Vegas properties, not the other systems. Wyndham owns RCI so obviously they can do what they want, and they certainly are.
As well, for stays under 7 nights, a housekeeping fee would previously apply to only point accounts. Not so now with Wyndham properties in Vegas. Anything under 7 nights triggers the extra cleaning fee, regardless of whether points or weeks. Other systems in Vegas still have extra cleaning fee for only point owners less than 7 nights. So booking any week in Wyndham Vegas properties, which you cannot even get the full week, triggers the housekeeping fee.
