So I guess I found out about Andrew a bit too late, as he is already booked for my early May travel dates. He offered to provide his associate instead. I'm wondering if it'll be the same experience. After all, a person is all that makes a difference. Would appreciate any feedback.
I guess John's reply in this thread answers my question.

We too were disappointed that Andrew is not available when we will be in Poland for our second adventure. Andrew made our first adventure so outstanding (a few years ago) and wonderful that we are gladly accepting his offer to recommend an associate to us for our visit in several weeks time. We are sure Andrew will only want the best for our second Poland visit and have total confidence in his offer.
