Checked into a ground-floor room at the Hampton Inn - Sea World San Diego last Friday afternoon.

I didn't notice until Sat morning that the patio door was unlocked the whole time I was there. Both the door latch and the safety bar were in the open position.

I neglected to notify the management because I was annoyed and was leaving that morning. Also, nothing was missing from my room, despite me leaving my laptop out in the open in perfect view through the glass patio doors.

Has this happened to anyone else? I don't expect any compensation, but would it be out of line to write a letter to that hotel's manager?
