You have an amazing husband! I would recommend purchasing your tickets ahead of time, as the ticket lines can be busy at the show itself. If you attend any classes, I believe admission may be included for that day.
You definitely need to plan one full day to look at all the amazing quilts, because they are all wonderful. Then there's the shopping! So many of the top quilting products are there with products and demos! Easily another 1/2 day plus!
I hope you have a great time!
