At that time of day when housekeeping is generally making their rounds, and especially if we plan to still be in bed sleeping or otherwise engaged, we make sure that all precautions are taken to keep housekeeping out of the room- DND sign and lock on the door. A reasonable person would assume that this is a chance you take in a hotel room that time of morning. Now, I will say that they should have knocked first just to be sure no one was there. That is their fault and I would expect them to apologize for their mistake, but I would never expect monetary compensation when no harm was done (other than maybe an embarrassing moment). Unless there is more to this story, I believe you are being a bit unreasonable to expect more.
