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?.

A tiny sticker helps housekeeping and front desk staff quickly identify which rooms are in which category.

4. Temporary Instructions for Staff

mark rooms reserved for a wedding party

designate rooms for early check-ins

block rooms for a group booking

flag rooms staff shouldn’t reassign

A small dot is a quick, discreet way for staff to stay organized.
