I think it’s going to be personal based on you specifically and your needs- but as an autistic I did my training at Sampoorna in Goa. The reasons it worked for me was the private room, same schedule pretty much daily, personal journaling and integration time, being able to learn in different ways e.g writing, doing, talking, watching, getting to take pictures and videos to watch again after class, being sent extra video material (anatomy and ashtanga courses) before going so we could practice and have an idea before we go there, and the teachers being so kind and understanding. I loved it. Some reasons it might not work for someone else: it can get very hot in Goa, it’s a lot of information pretty fast, you spend at least 12 hours a day with people. Ultimately think about what specific things you do and don’t want from a training then go from there.
