Sure, just let me know once you know where you'll be and I'll try to find a good teacher there. The best place in Brazil for belly dance is undoubtedly São Paulo though, so if you have a chance to stop by there sometime, you won't regret it... that's where it's all at!
But in any big city there are probably good dancers I could recommend.
I'm not sure what my itinerary is going to be like, but why don't you come to one of the shows or workshops? If I have time, of course we could schedule a private. I won't know what's up till its closer to the date.
Oh I think Didem is great She's awsome technically.....but as for a more lyrical bellydancer I'd would then say I've been into a russian bellydancer by the name of Maria Shashkova - SOOOOO amazing and expressive she is! lol
