I'm happy about this change. It will probably help generally with villa cleanliness as while some people take the trash out on their own, others don't, so the build up can lead to unpleasant smells and bugs that can linger...

I personally do not travel with anything of value that does not fit in a hotel room safe so I could care less about hotel staff coming into my room. Be it DVC, a regular Disney hotel, or any hotel elsewhere, I expect staff to have to enter my room for various reasons and I plan accordingly.
