Upon first checking in, find the small envelope for housekeeping gratuities. A good general rule for housekeeper tipping is to place three to five dollars per day in the envelope. Leave it in a place where the staff can see it while cleaning the room.
Plan ahead. Housekeeping staff are on their feet almost all of their shift. If you know you want turn-down service or extra pillows and blankets, call in the morning asking for this so the staff plan ahead and do not need to make extra trips to the room. It is amazing how a little forethought gets noticed by staff.
Speak with the head of housekeeping and explain if you need special service or have any concerns. Do this proactively. For example, if you have a down allergy, ask the head of housekeeping if they would place non-goose down pillows in the room. By speaking with the head of housekeeping, you ensure the request is received and someone is accountable.
Give praise to the hotel manager for a job well done on the housekeeping staff's part if they do the job to your liking, especially if you stay at the hotel frequently. Staff remember, and if you sprinkle praise to the higher-ups, you typically get special treatment and consistent service.
Learn a few words in Spanish such as "Thank you," "Please," "How are you today?" and "Good job." Today, it is very common to encounter Spanish speaking-only hotel staff. By taking the time to break through the language barrier, you show how you treat people with dignity and respect, and that goes far in receiving consistent housekeeping service.
