We have had staff (specifically restaurant staff) recognize us, which is sort of interesting since the woman that mans the egg station at Caneel Bay likely wouldn't see our guest profile in the reservation system. She always remembered my husband and the specific way he wanted his eggs cooked.

At our most recent stay in Philadelphia (at the Sofitel) the waiter greeted our son with a "Nice to see you again. Do you still like hot chocolate with extra whipped cream?" It blew his mind that the man remembered him and what he liked at breakfast.
