I havent attended any full course, but i have spent a week in the jersey residences and visited the zoo over and over againg, i was also allowed to attend 2 clases of the DESMAN course that was being held. I found incredibly interesting the course and the rooms are also quite nice, only proble was that i slept on the uppermost floor in the thylacine room, and the bathromm was 1 or 2 floors below so i had to come down to use it. But it was worth it, appart that you get to know people from around the globe and make friends. Not forgetting that the food is delicious, and that you get to be in a library full of Gerald Durrell´s books.
I really enjoyed my time, and hope to do a full course in the near future.
