Advice on Las Vegas gratuities

Valet parking attendant: $1 to $2, but only when you get your car. If the hotel charges a service fee, be sure to ask what it covers; it may include gratuity.

Bellhop: $1 to $5 per bag, depending on the level of the hotel.

Hotel doorman: $1 to $2, especially if he helps you get a cab.

Hotel maid: $1 to $5 a day, either daily or in one lump sum at the end of your stay. Aim toward the higher end in upscale hotels.

Room service waiter: $1 to $2 per delivery, even if service charge has been added.

Hotel concierge: 10% to 20% of the cost of a ticket to a hot show; $5 to $10 for making dinner reservations or arrangements to other attractions.

Dealer: Tip the equivalent of your average bet once or twice an hour if you’re winning; slot-machine change operators or keno runners should get $1 to $2.

Cocktail waitress: a $1 tip per drink is appropriate, even when you get a free drink at the slot machine or casino table.

Taxi driver: 10% to 20%, but round up the fare to the next dollar amount.
