I have mixed feeling about this too. Depending on how fancy our home has been, our feelings about this have changed over the years too. We do appreciate our surroundings but the elements that matter more have dramatically changed for us over the last decade - and it's been due more to our change in circumstances (and the ages of our travel party) than to what our home is like.
When we started timesharing, we were wowed by fancy, upgraded kitchens and baths, extensive kids' activities, lounges, golf courses and tons of space in the LR for us all to relax together in the evenings. But with 3 kids and their friends along, we adults felt more like we were on vacation too, when we had all those things. A bit of pampering in the midst of 24 hour Chaperone-ville, I guess.
Now, with the kids all grown, just having a good pool, hot tub and computer access within walking distance is what they want the most. A pool table and/or ping pong is a hit. Being able to walk, bike or drive a short distance to sights or shops is nice too but not really essential as long as its within 20 minutes drive or so.
For us adult parents, location matters! A clean, quiet and well-maintained unit with a decent kitchen, a washer/dryer and a comfy bed are highest on our list. A beautiful view and a pretty and safe place to walk outside in the evenings and computer access have all crept up in the priority list as well. (Never used to care.) The pool, hot tub and good proximity to the area sights are all close but not deal-breakers.
The whirlpool, upgraded kitchen, nicer furnishings, fancy clubhouse, golf course, etc., have all dropped way, way, way down for us. Funny how the things that appeal can change so much over time!
