Dear James:
Never fear, you won't get stuck in the hotels. Contact Edward Germanov at
baagoron@aster.net. He is President of the Bulgarian Aikido Association which is a member of Aikido Association International. He was a direct student of Fumio TOyoda Shihan and leads a rather large group of dojo throughout Bulgaria. In addition, right at the end of May, they are hosting an AAI seminar (the exact dates I am unsure) with Andy Sato Sensei instructing.
