We cruise several times a year and we also travel with friends on a private yacht. The Evolution had the luxury of cruise ship with elegant bed linens, amazing service and crew, but the intimacy and flexibility of a private yacht...at a very affordable price!
First I would caution anyone planning this once-in-a-lifetime trip to not be land-based. Day trips require many hours back and forth in small boats and only the ability to get to the most frequented islands. Also, it is a waste of your travel dollar to only spend 2-4 days on the boat or to cut the trip short for Machu Picchu or other add-ons. Plan 2 weeks if you want to go to the Peru, Amazon, or explore Ecuador. The latter is very reasonable and quite amazing in itself.
Our group of 32 family, friends, and associates was not an easy one to organize or to please. Most are discerning travelers and many are budget-minded. We had diverse abilities, needs, and expectations—and everyone ended up with nothing but praise and also awe at this one-of-a-kind interaction with nature, science, and culture with very intense encounters with nature while feeling pampered and respected. (You can, of course, just book a single cabin or bring a family along.)
We had the largest cabin: the master suite with a comfy queen bed and luxury linens. The bath was larger than on most mega ships and had a door that opened out onto the deck. It was quiet and just behind the bar and main outdoor seating area. Perfect location! However, our group of 32 people and we were all satisfied with our cabin choices. Most said they were larger and better appointed than expected.
