The Golden Eagle is an awesome excursion. We just did it 2 weeks ago. Be prepared to get wet. The water was really rough and we were sitting in the nets. We were soaked completely within 5 minutes. But hey it was 30C and the water was warm. If you get seasick easily, sit in the back of the boat and maybe wait with the open bar until the return trip. The crew on board was great and trust me, it's not boring. We even had a CCL videographer on board, all his footage is on the DVD we bought later at the photo shop.
Have fun !!
