Yeah, sorry for my misleading post about the extra points. I do get the points multiplier on my Marriott card, but I did not earn points on the charges to the room for the Seaplane, the baggage fees, the PCR tests, or the meal plan. I will blame my mistake about points for the baggage fees on the jet lag and the 40 hour journey home. ha ha
I do find it interesting that points earning did not occur on the meal plans. On the days I was not all-inclusive, I earned points for those meals. As an aside, I was able to do the all-inclusive plan for the 6 full days I was there, and not the arrival day (arrived at 1p) and the departure day (departed at 3p) which was the check in agent's suggestion.
