This expedition is great, Joan has a great passion for dolphins and the marine environment and it is very easy to see. This enthusiasm makes the trip much more worthwhile and you can see that he appreciates you being there to help. I would recommend this to anyone interested in anything to do with the marine world. I saw dolphins more days than I didn’t, I saw them socialising, feeding, resting and I even heard them playing. As long as you understand it's not just a holiday and there is science and work to be done, you will have a great time as the balance between the work and experience is very good.
