swainj,
I guess "mixed revues" are common for many resorts. We've had very nice Villas while others complain.
This is for Desert Springs Villas II: From a recent newsletter/Board Report/Financials, the first 136 Villas were refurbished this summer. Next summer, we will refurbish another 128 Villas. The last 138 Villas, including Jasmine Court will be done in 2009. Of course, getting one of the refurbished units would be the big question. (1 in 3?). Personally, stay away from Jasmine Court. While part of DSII, it is separate.
The JW Hotel is well within walking distance, however a shuttle service is provided too. Charges can be made to your Villa.
Most views are typically of some part of a golf course. All views are considered 'Excellent', but some are nicer than others. Desert Springs, and probably most resorts in the area seem to have on-going housekeeping problems due to the help situation. DSI & II have a new "wordless" training video implemented in the Housekeeping Department.
I have no info on DS I, as we don't own there. They are effectively one resort area though, with same check-in desk.
I really think you won't go wrong with whatever your choice may be. Most everything is close-by, from a WalMart & Costco to high end shopping on El Paseo. Restaurants abound.
