We sailed from San Juan , 1000 miles up the amazon river, hit cities in Brazil including Rio; visited Montevideo and Buenos Aires. Great itinerary.
The crew were all great, without exception. We say the hotel GM every day. The Captain made a point of visiting several times during the cruise - before this, I only say the captains on formal nights or as a special exception.
The stewards were, likewise, very friendly and efficient. Filtered water every day, plus we asked and received two bottles of water every day. The refrigerator had snacks and soft drinks replenished daily.
The cabins are fine, all Verandahs. The ship had a bit of an issue keeping constant temperatures -- but we were on the equator, after all. It was nothing intolerable, just a challenge to get everything the right temp. Bathrooms are just as advertised -- spacious and clean/bright.
Embarkation was almost too easy. Luggage was available almost immediately.
Our first stop on the Amazon. We went Piranha fishing with a tour through smaller tributaries to see wildlife and local people living off the river. Outside the city is very sparsely populated with primarily individual houses alone.
