On our Splendor TA this past March/April, we gave gratuities to butler, suite attendants, favorite servers and favorite bartenders (looked after us very well!). We also gave the room attendants candy indigenous to the Savannah area, and they were gobsmacked by that. To the point, our main cabin attendant told us that in her country, receiving candy from people is highly prized. May be something worth looking at doing for excellent service.
