Always wanted to visit the Galápagos and surprisingly, with an offer they had on, this was the best deal (don't get me wrong it was still expensive). Due to the location only small ships can go there, but that was part of the experience. We got to know many of the staff and customers very well.
The trip was amazing. We saw creatures you never see anywhere else.
The expeditions were very well organized and the guides were fantastic. Snorkeling was great - don't be put off by the deep sea snorkeling, if I can do it you can. Most wore wet suits, we didn't and it was fine, however the water is warmer (ish) this time of year, so when colder probably worth wearing one.
