LuCruise, thank you for answering my question and supplying a copy of the perks letter.
While the family members I’ve booked have decided to purchase the drink package and remain in the Promenade cabin directly across from my ocean view balcony for our upcoming cruise, they said maybe the next time.
For anyone one who might be interested, the Ben & Jerry Sweet (6305) was still available as of yesterday for the Independence April 29, 2019 sailing and it’s possible it might be available on a sailing you have already booked. For my cruise it doesn’t show on up Royal’s USA .com site (that only lists some cabins and I can’t find a way to search for a particular cabin like you could in the past), but Royal’s UK (.co.uk) site lists ALL available cabins. So check there if interested in booking or switching to that cabin.
