Regent offered the best itinerary and time of the Amazon River...hence we booked it!
A careful evaluation on our return home leaves me with the following comments:
The best..."all-inclusive" means just that...you pay for nothing - wifi, shore excursions, specialty restaurants, booze, friendliness of the crew, gratuities...nothing!
Good location...far enough from elevators and the self-service laundry, but convenient enough to save steps. Only one problem...on rougher days/nights at sea, there was a noise coming from the head board wall that was very annoying. Response was quick to my call, however it was the story of taking my car to the shop when it makes a "funny" noise...couldn't get it to repeat when crew was present. Oh well, get ear plugs.
This cabin experiences non of the vibration mentioned in other reviews.
