I think the OP is experiencing the same concerns about housekeeping that most new DVC Owners do. Some owners do pay for daily housekeeping, but the vast majority of owners, once they experience no daily housekeeping, like it.
When I leave my room in the morning, I make sure the entry door are all locked securely, especially the one bedroom/studio connecting door. I've never had anything go missing, including electronics that I've left in plain sight. If I had daily housekeeping, I'd feel the need to tidy the room up a little and secure/hide laptops and other electronics, and in a way, now on housekeeping days (while I absolutely appreciate the fresh towels and freshly made beds) I feel a little "put out." Plus I usually do leave a tip for the housekeepers. I think the rooms, from a maintenance standpoint, do need to have a quick walk through by a housekeeper every few days, so I wouldn't make any changes to the schedule.
