Enjoy the Pinnacle suite! We had a Pinnacle suite in 2020 and have it again in March and I can't wait.
Fridge:
All nonalcoholic drinks in the fridge are included with the suite. Anything alcoholic you have to pay for (just ask your room steward to remove them.
Included:
Canned water, Sparkling water, Coke, Diet Coke, Sprite
In the main room they will leave a bottle of prosecco as an embarkation gift and a large bottle of water (which they will replace for you)
A word of warning about the fridge/freezer. It is an industrial style unit and ours stuck every time we opened it and you had to make sure you really pushed to fully closed it.
Tea kettle
I'm 90% sure we had a kettle, it was in one of the many cabinets. They is a box of Harney & sons individually wrapped teas in a tea box on the counter. If you have a favorite, don't be afraid to ask the stewards to stock more or less of specific varieties. (This also works for the Nespresso pods, as I like decaf in the evening).
If you do get tea delivered to the room they send an assortment of tea bags from the Lido not the nicer ones. But they do send a carafes of hot water .
