I did mention the speech in my query [which my TA forwarded to Ponant] but the rep did not address it.
“People on CruiseCritic have been debating whether grats are included or not, especially as they’re not listed in the inclusions on the Ponant site. Apparently, Ponant leaves envelopes for cash tips in the staterooms and on a few sailings, the officers have made announcements encouraging guests to tip.”
