There were two scotch tastings, one on Friday night and one on Saturday night. On Friday night we didn't think to make a formal announcement, so some folks missed out (Sorry!)
But on Saturday night we made a formal announcement, and everyone within in earshot who was interested (some folks were apparently out for a walk, etc.) was able to queue up for a taste.
I don't really have suggestions for improvement, In large groups I tend to be a "go with the flow" type of person. I had a great time! You did a great job planning the event, and it worked well for me. If I'm in the area when the next one is scheduled, I'll be there.
