Just returned from a 16 day trip to Peru. The first 5 days were spent on the Aqua. I am posting this information due to the fact that when I orginally wanted to book this boat, I was unable to find any information on Aqua Expeditions because they were new. We only booked the 4 night trip because we heard that 7 days became repetitive. 4 nights ended up being just perfect. The Aqua is a beautiful boat that exceeded my expectations. We had a total of 21 passengers on board all ages and nationalities. The staff, guides, food etc. were amazing! You could lay in your room and just watch the banks of the amazon go by. The observation deck had cushioned lounge chairs you could lay on or you could go into the glass enclosed bar area that had chairs and couches to relax on. There were books, puzzles and cards to use also. The food was the best! The menu was very diverse and there was something for everyone. The guides and drivers were outstanding, always searching and finding things in the water and trees. The staff was friendly and truly appreciated the guests. This boat may be a little more than the others, but the experience is priceless. If anyone has any questions, please feel free to contact me.
