If a Saturday date you desire has been been booked, consider a Friday wedding. Fridays are becoming more and more popular, and truly are desired by many couples. 
This grants your guests the opportunity to experience Nashville for the weekend. 
Either way, it's a great weekend for your guests, as Nashville has been rated # 4 in the U.S. for a destination wedding.
Please note that if a date is pending, it will not be shown as booked until under contract.
Therefore, a date may show as open, but is actually pending. Thank you.
