Embarkation went smoothly and in no time we were on board with Champagne in hand and our first trip to the buffet. Things went smoothly and although our luggage took quite a while arriving, we were on vacation so what.
To ease the pain let me skip to things already covered by other cruisers.
The Captain and cruise director. Exactly what you have read but they both disembarked in Buenas Aires for a 4 month vacation so there is hope in that area.
Our cabin was standard for a balcony on most cruise ships. The bathroom is tiny and the room between the one end of the bed and the storage was difficult to pass through. We are not heavy people but I could see that it could be a real challenge.
