Is the following review positive or negative?

Normally we love the white water center. It is a GREAT place for rafting, kayaking, rock climbing, mtn bike riding, etc and my kids love it. The issue is that we booked their private conf area for a large family event (~200 people) over 6 months ago and were told that there would not be any other events that evening. 3 weeks before the event (in the middle of wedding/graduation season) we find out from a friend that they have a large public concert event scheduled that same night. Not only is that a major issue / conflict with our event, BUT they didn't even inform us of this. They offered no flexibility and no apology for this. On this short notice we had to find another venue as we were not happy with competing with a large public concert for an important family event. I would discourage anyone from booking a private event there.
negative
