The points needed for my stay are the most important. If I can book a one bedroom for three or four nights for fewer points at one resort over another, we take the point cheaper one. We try to stay mostly in one bedroom villas and own most of our points at OKW. So we stay often at OKW. We have one small 50 point Dec contract at OKW as well, so we usually use that for three or four nights in a studio at OKW in early Dec. What I hate about refurbishment is that they usually take away the theming instead of working with the theming at the resort. While the outside stays pretty much the same, the villas inside tend to be more and more generic. We loved the early years of OKW with peach colored towels, place mats, beautiful colors inside the villas as well as outside. Now they are bland (and sometimes ugly), towels are the standard white and placemats are gone. The artwork gets cheaper and cheaper looking with more cartooning instead of themed artwork. This past year we were able to use our points for one bedroom villas all over the place and we've pretty much stayed at most of the resorts on site, except for Riviera where we probably won't stay.
I really don't care about modern or not. I just want a clean villa, a comfortable bed to sleep on and a comfortable chair to sit on. Usually the clean villa and comfortable bed are there. Often the comfortable chair is missing. I prefer a stand alone shower over stepping over the side of the tub to get into the shower, but that happens every so often (like OKW studio).
When it comes to other resorts, they do change. For instance, VWL was more like NW US National Park, more specifically Yellowstone. When you go to Yellowstone, the rooms still look basically the same, other than slight changes to the room (we've stayed in several of the hotels or cabins there over several years). VWL went from NW US to SW US National Park with the Native American theming in the carpet and other places. It used to look more frontier, cabin-like. Now it looks more modern. Copper Creek is Ikea-woodsy. And it will all change once again when they start the renovation there later this year (or early next year). We bought our points at VWL because we used to live in Montana and went to Yellowstone often.
