You are correct in all regards. We have had a concierge contact on recent cruises on Crown, Emerald and Grand. These were in late 2023/early 2024. We were never charged for ordering DR food by phone. We also had suite only cocktail parties as you describe on all sailings. We were able to use our concierge contact for many things, just like the Concierge Lounge concierge on the newer ships (reservations, tenders, disembarkation, special requests, etc). We have 8 more bookings on the Grand and are looking forward to the extra help!
