My mom checked into her hotel and noticed a tiny blue dot sticker on the door. She’s freaking out—what does a blue dot mean?.

⚠️ When SHOULD a Sticker Raise Concern?
A marking becomes potentially suspicious if:

it appears recently and is not used on other doors nearby

it is hand-drawn (chalk, pen, X, slash marks)

there are multiple different symbols appearing over time

someone was seen loitering or marking doors

the location feels unsafe

the hotel is poorly staffed or unresponsive
