I would have them in hand just for ease of entry. You will want to spend several days there for the vendors alone. I think there are over 1,000 or that is the way it feels. If you see something you like, buy it. It's almost impossible to return to the same vendor. I spent many hours trying to backtrack to find that one thing I wanted. Just remember to tell your credit card company that you will be at a show. Several of our members had their credit cards flagged till they contacted the company. When making purchases, the vendors are from all over so it looks like you are in California, then Minnesota, and so forth withing a few short minutes. Enjoy!
