We found the ship to be an ideal size 24 rooms each with a large window, 48 passengers and a total of 32 ish crew (including crew members and naturalists). The food was very good, the staff accommodating, the naturalists ranged from passionate to capable. Safety - of the passengers and the wildlife - seemed of the utmost concern to every member of the team.
Excursions were many and varied and we recommend you take as many as you are able.
Initially, we'd had some reservations about the level of activity that would be required of us. The spirit of adventure captured and transformed us into hiking, snorkeling, kayaking Grandma and Grandpa to no ill effect.
Plenty of room for two people. Enjoyed the large window most of all.
