We meet with the concierge staff upon embarkation to review dinner reservations, confirm our table for two, confirm our cabana (which is probably the most work they've done for us). Maybe we sign up for a tasting. That is the extent of our neediness, if you will. For that, I could fathom a 100$ tip per day, if I were independently wealthy and wanted to share the love. I enjoy each of the concierge team members. But in all our cruises, it had always been our cabin steward who does the most for us and goes really above and beyond. Cabin stewards have a recommended tip of 4$ pppd. So for the two of us, that's 8$ day. We double that since our room is larger and has an extra bathroom. The concierge team is warm and friendly, and we think highly of them. But given the comparison to the room steward who is scrubbing my toilets and sometimes fills a night dress I've tucked under my pillow, doesn't lead me to tip concierge more than my room host. With the recommended rate for room steward being 8$ a day, we figure 10 wealthy $ a day for x number of days and then round up. For example, 4-night cruise = 4 * 10$ = 40, round up to 50. 7-night cruise = 7* 10$ = 70$, round up to 100$. Whereas our cabin steward would get 16$ * 7 nights would get 112$, round up to 125$. And yes, we tip the bartenders and food people in the lounge, as we go. Coupla bucks here and there, then a, twenty at the end of the cruise with a nice nite they can share with their supervisors.
My logic may baffle some, but it doesn't matter if it does. Ultimately its everyone's private decision to make and live with. My logic may be leave you thinking that I drink from a cup of the crazy. That doesn't matter. What matters is that I've come to my own logical (in my head anyway) process at how to arrive at a, fair tip. Tipping is always a personal decision. Just make a decision you can live with. That's all.
