The matter of preferences entered into one's profile was recently discussed here. The picture I got is that once you get past room type preferences, nobody pays much attention. This goes for the hotels as well as the guests. I guess I'm one of those. My profile calls for a fridge and extra feather pillows. 80-90% of the time, I get neither. But its not a big deal to me, so basically I don't notice it....much less complain.
Frankly, I wouldn't expect any significant improvement here. My guess is that fulfilling what's on guests' profiles beyond room preferences isn't a priority because collectively customers don't appear to have made a big enough issue out of it.
