Hi. We went on this trip in March & loved it. Very casual, but bring good walking bots for Macchu Picchu & water shoes/sandals for Galapagos. We needed the altitude sickness medicine. Some people didn't, but some were sorry they hadn't gotten a prescription, "just in case". It was a well paced but challenging trip if you tried to do all the hikes & snorkeling. Hope you have a great time - shared with a fun group. (we did).
