• Some of the best whale and marine-life encounters you could ever have – with fantastic company on a great boat. The sight of a blue whale and calf surfacing right next to our boat will stay with me forever. Alan Airey, Moray, Scotland

• A truly amazing holiday, awe-inspiring whale encounters and stunning scenery, coupled with the professionalism, knowledge and humour of Mark and Rachel, made this a trip that will be difficult to surpass. Debs Cole, Worthing, West Sussex

• For years people told us they had been whale watching and were thrilled if they could see a blow in the middle distance. We saw humpback, sperm, Bryde's, pilot, fin and even blue whales right beside our boat – and we touched greys in San Ignacio lagoon. I'll never forget it. Steve Connah, Inverness, Scotland

• The key experiences for me: blue whales, especially the fluking ones; dolphins at night lit up by bioluminescence; stroking a whale; being a matter of metres from a breaching humpback; seeing a rare Peruvian beaked whale. But most important was the enthusiasm of Mark and Rachel. Chris Goody, Saffron Walden, Essex

• The whales and dolphins of Baja California alone are more than enough to make the Baja trip worthwhile. But there is so much more: a fantastic, good-natured crew on board, lovely fellow-travellers to share enthusiasm, excitement and knowledge, great photo opportunities, excellent food and cosy dinners. And all of this under the inspiring guidance of Mark and Rachel: their passion and knowledge made the trip even more unforgettable. Charles and Els de Haan, The Netherlands
