I've also done multiple Vipassana retreats in the tradition of Goenka. There were "office hours" (around lunch and after the evening meditation) where you could ask questions. I found that the quality of the answers given depended on the quality of the specific teacher. While I was impressed by one teacher's answers, I got a similar "just keep meditating" answer from another. That being said, Goenka's centers are free, and have a structured routine with no distractions, so I continue to recommend it to others as a first course.
