@oufpat The answer to your question is it depends on the 
travel agency.  We decided to surprise our son with an 
ABD Backstage Magic trip as a high school graduation gift.   Yes, the booking discount is nice, but as 
@riot23 mentioned it is the agency experience that sold me.  
I submitted a quote request to Dreams Unlimitied Travel asking to speak with someone who has been on this adventure.  The next day 
@DisneyKevin called me.  Having been on this adventure numerous times, he was able to answer all of my questions and gave recommendations on booking pre and post nights.  
I highly recommend Dreams when booking ABD.
