We had a memorable and enjoyable cruise, with only minor irritations. The itinerary was generally excellent, particularly the Rio de Janeiro to Miami segment. Cruising the Amazon River was spectacular, and only could have been done as well in a ship of Regatta's size.
The ship's staff was generally excellent. The Cruise Director, Dotty K., was everywhere every day. She saw guests off on excursions or visits in the morning, reminding them to take an extra bottle of water to keep hydrated. She was throughout the ship in the afternoon. She hosted the evening show (and always beginning with, "But first, a joke...."). She kept things running smoothly, but always had time to listen to passengers wherever she was.
Food was uniformly excellent in the dining room, and very good in the Waves Grill. The ship did not have the grill in Waves that Marina and Riviera have (but it will by now), so grilled entrees were lacking there. Staff was amazing. The Executive Chef went through the dining room meeting and greeting on several occasions. One night, my wife asked him for his recipe for miso glazed seabass, her favorite dish on board. She actually received it the night before we disembarked!
Cabin was generous in size and well appointed. We did not use all of the storage space provided, even for 33 days on board. Our cabin steward and butler could not have been more helpful -- they anticipated our needs on many occasions, and we did not have to ask for most services. Reservations were made in specialty restaurants for us. They learned quickly which beverages and canapes we liked, and supplied them even when we did not ask.
