I can't speak for this one, but it's similar to the pre-conference training that is offered before the PASS Summit conference and most people see value there.

Andy has written a few SSIS books, speaks on it at many events, and has done this type of training before. If you need more details, I am sure you can contact Boston SQL Training or Andy through his blog (http://sqlblog.com/blogs/andy_leonard/default.aspx) and he can answer questions.
