My fiancée and I went on the 08:30 excursion and it was amazing, easily the best excursion we've ever been on. It was well organised with a shuttle bus that picked you up near to your hotel in the morning with clear instructions on where the pick up point is, we got a little confused on where we were dropped off when shuttled back but the bus driver called our name to let us know it was our stop.
The staff were friendly, helpful, knowledgable and clearly loved what they do, they really made you feel like they wanted you to have the best experience. They organised the seating on the boat so there wasn't any fighting or scrambling for seats and when arriving at a pod of dolphins they let the people sitting in the middle or the back of the boat walk around to see the dolphins on either side. They provided blankets for the trip over to the dolphins and back (as it did get a little cold with the wind and it being quite early) as well as information on the dolphins themselves as well as the local area. They were all very enthusiastic and were willing to take photos/video for people as well. The trip online says 2 hours which is fairly accurate, and for our trip I would say it took around 40mins to arrive at the pod, 40mins seeing them and then 40mins back.
We have seen glimpses of dolphins before, but having a decent time there meant we got a lot of video and pictures which all added to experience. They dont feed or interact with the animals other than following behind slowly so it was very respectful and just about seeing them in their natural habitat. All in all we would say it was the best all round experience on an excursion that we've been on before which warranted the 5* review. Would definitely recommend for anyone visiting the area.
