This is exactly how it was implemented on our NCL Prima 10 day out of Amsterdam on 3 September. ( 1st paid passenger cruise)
We are both Platinum
We received a Platinum Latitudes coupon booklet (actually a folded piece of lightweight cardboard) that had a coupon for 3 things:
1 - dinner for 2 with bottle of wine
2 - dinner for two
3 - free bag of laundry
notes re #1
— this can’t be redeemed in Palomar because Palomar has a unique wine list that contains only organic or biodynamic wines
— we redeemed it at Cagney’s, where we could select bottles only from a much pared down list. I think they were all on the UBP plan to start with. I need to verify, or you can if interested as I posted the dailies and most menus to my live report (entitled “not quite live …”)
— we EACH got an app, salad, entree (25 extra for tomahawk and lobster), 2 sides, dessert. A lit of food! A la carte pricing totaled about $150, zeroed out by coupon.
notes re: 2
– the coupon was good at any of the restaurants
— we used ours at Onda (excellent BTW), where our bill was about $120 before the coupon and zeroed out after the coupon.
— We each had an app, entree (main to the non-US) & dessert and shared a pizza for our starter. Again a lot of food.
Relatedly, we also has 1 free specialty due to FAS and 2 specialty meals that we purchased as a package (hint - much cheaper before you embark). we used these as follows:
— Los Lobos - app/starter, entree, side, dessert
— Food Republic - 4 items each person.
— Palomar - salad, starter, entree, side, dessert
— if you don't have enough specialty dining, you could do Los Lobos or Food Republic out of picket. We were pressed to get $40 each out of Food Republic with our preferred choices (but since we paid for the specialty dining I wanted to get back at least what I paid)
notes re #3 (laundry) I inquired at Guest Services (Latitudes/Future Cruise desk was closed ) how to get our 2nd laundry coupon as we are both Platinum and this is a per person benny, not per cabin. I was told to just write “Platinum” on the bag and slip, which I did. No problem
— since we were in Spa Balcony, we also got 2 more bags of laundry, they said just write the same info.
Also for Latitudes benefits they weren't doing the behind the scenes tour “due to covid”, which I call shenanigans on - the latitudes cocktail reception was packed as were mist entertainment venues (no special distancing required). And the “Round the World Wine Tasting” was capped at 100 and full before we got onboard (per the Latitudes staff).
