We have attended the last two years and it seems that Sammy likely plays the 7th, 9th, 11th, and 13th regardless of day of the week. Is this pretty consistent or is there any likelihood that those days change? This year that means we would need to be there Tue to Tue if staying for one week, but I want to feel comfortable that there isn't likely to be any changes to that pattern before booking a flight and room. Thanks to anyone willing to help here.
