Generally, this is a good resort. I plan to stay there in mid-January in the Cascades section, which is one of the newer sections. Fountains I, Fountains II, and I think maybe the Lakes are also new sections.
There are some older sections of this resort, though, which are not as nice. I seem to recall that the older sections are the Springs, Courts, and maybe the Spas, but I'm not sure. If you do some searching here, you should come across posts that not only tell you which are the new sections, but also which unit sizes and which check-in dates may be in the older sections. For example, I believe that all 1-bedrooms are in the newer sections, as are all or most 2-bedrooms that sleep 8 privately. 2-bedroom units that sleep only 6 and have Saturday check-ins may be in the oldest section -- I think.
