Hallo, my name is Carla Sabatini, I was a teacher of tourism in a vocational high school in Rome and now I am retired, but I am still interested in the tourism sector. I wrote three school books about accessible and sustainable tourism and now I am writing another work on the same topic. I take part in this course because I think I have always something to learn. Many greetings to all of you I had the pleasure to meet in Perugia last year.
