Stayed in concierge twice, first time on Magic, this was our second. On the Fantasy there were some noticeable improvements but also minuses:
Embarkment: very smooth, we were on the ship within 15 minutes
Concierge Lounge/Concierge Service:
Great cabin, great view of castaway cay and fireworks on pirates night. Quiet and super convenient next to elevators and concierge lounge. "Pichet" our room attendant was wonderful and always put us in a great mood. All issues reported to him were quickly resolved. (toilet issue and sliding door which wouldn't lock). All were corrected.
