Today, even the seasoned traveler is unsure about who should be tipped and the amount/percentage they should receive. Tips should be earned and in most cases the amount that should be tipped depends on the level of the hotel and the level of the service.
For the business traveler, always make sure you have at least twenty $1.00 bills.
Taxi – 10%-15% of the total fare.
Limo – 15%-20% of the total bill
Shuttle driver – $1.00-$2.00 per bag if the driver assists you.
Baggage Handler/sky caps – $1.00 per bag
Special Assistance – If you are traveling in a wheelchair or with crutches, for special assistance from airport staff, tip at least $2-$5 to the employee who assists you.
Hotel Bellman – $1.00 per bag for delivering bags to your room; $1.00 per bag for retrieving your bags from storage.
Doorman – $2.00 for getting you a cab. Also, if you need to deliver something to a hotel and will only be inside for a few minutes, asking the doorman to watch your car that is parked in front of the hotel requires at least a $5.00 gratuity.
Housekeeping – $2.00-$10.00 per night depending on how expensive the room is and how messy you are.
Room service – Almost all hotel chains add a 20% gratuity to your bill automatically as well as a $2.00 delivery fee when your food is brought to your room. If this is the case in the hotel in which you are staying, then no tip is necessary for room service.
Additional charges – If you ask for something additional to be brought to your room, a $1.00 tip is suggested.
