Tipping is very personal. You decide what you can afford. Also, we save our tips to the end of the cruise for our butler, steward and concierge. Some tip them as they use them. Many use the $10 pp per day rule for the butler and adjust up or down based on service. Room stewards’ tips based on service. We often tip them the same as the butler despite being part of the DSC since they do the most to keep our room tidy and clean with the concierge getting about half as much. We tip bartenders as we are served and same for waitstaff in restaurants - Haven, included restaurants and specialty ones. Haven Head maitre D’ at the end of the cruise and amount less than our butler. Around the ship, we tip as drinks are served or for dining service at the time. Again, you tip what best fits your service and your custom.
