We will be visiting for a week in Nov with 5 adults, 1 child and 2 infants and using the DDP. When I made dining reservations, I was told an automatic 18% gratuity would be added to our bill as we will be a party of 8. I don't have any problem being gracious with a tip but has any noticed that the wait staff isn't quite as attentive when they already know what there tip will be?
