Thank you all! I saw the times listed for the days we are there, but just didn't know if they had a set place on Main Street to go. I'm willing to be flexible, but just didn't want to be waiting in one spot just to find out I was at the wrong end of main street. We have 3 days, so I am determined to see them this year.
Last year when we were there we saw a group performing around Pirates. It was unplanned and unexpected. We spent 15 minutes just watching and enjoying them.
