My husband and I are in our 60's, and traveled with our mid-30's daughter and her husband. We had read that this was the trip of a lifetime, but couldn't believe that it could be that incredible. We were wrong it was absolutely perfect. Other reviews have mentioned the details of the trip. We took the 10-day version, flying to Quito on Friday night. The Marriott Hotel was wonderful and we were able to have an upgraded room because we had traveled with Celebrity before. I need to echo the comment in Hoytj's reviewthe altitude is a problem. We had been to Cusco the previous year and took altitude medication, but didn't think we'd need it this time. We were sorry that we hadn't brought it, because it was almost impossible to sleep at night. The day in Quito was fine, but nothing compared to what awaited us on the Xpedition. The wonderful service began when we arrived in Baltra and didn't stop for the entire week. We arrived at the Xpedition by zodiac in time for lunch. Then we went on our first island excursion. We had two excursions a day, selecting between high and low/medium intensity. Every day was better than the day before, and we saw different wildlife at every stop. The naturalists were all wonderful. We especially enjoyed Myra. When we look at our fantastic photographs of the animals we still can't believe that we were that up-close-and-personal with so many amazing creatures. One comment about our cabin on the ship. We had decided to wait to take the trip until we could book a room with a veranda. Others have said that they felt this was a waste of money (it is expensive!), but we have to disagree. Even though we were off the ship much of the day it was wonderful to sit out on the balcony and relax with wine or a drink between activities and in the evening after dinner. The weather was perfectlow 70's all of the timeso we loved the veranda. All in all it was our best trip ever!
