Before I went the first time I asked for details from others on forums that went. I like it because you aren't confined to one big building where the quit show is. Everywhere it is all about quilts during the show. you can walk to the museum from the convention center, it's behind it.
Eleanor has a big QIAD in town and has her tent and sale barns at the fairgrounds. She is always there signing books and talking to everyone. Her son Orion is out and about helping with the fabrics and keeping the tents stocked. Everything is very casual and every one is very friendly.
You don't need to drive anywhere or if you do just follow the shuttle buses to go to every quilt spot. A big sign is on every shuttle list the stops it makes.
I am so glad I made the decision to go at least one time. It's the closest big quilt show to me so I would urge all quilters to go to a big show closest to you while you have the chance. They are worth it.
