I say "busy" is a good guess for a "normal" year, this year.... I'm thinking extremely busy and crowded. I would recommend having all stuff organized and your prices marked "CLEARLY". Having an assistant to cover your "human needs", you don't want to leave your table unattended. Also an assistant that knows how much you are willing to "adjust your prices", people will ask.( I've been told I'm cheap, But that's my wife's opinion)
If you think you will have time to go look at the models, have an assistant. Expect to meet many new friends. Be able to talk and do business at the same time. Have fun.
I look forward to see if you have something I don't really need but I just "might need it someday for that project that I don't have time to ever do".
I will see you there and good luck.
