Mark, Tucson John has been there many times. He can explain everything. If it was me I would make it an overnight but you don't have to. The gathering ends in the afternoon. After Marine rides and Yankee swap.
For the swap bring a wrapped gift, about $15, preferrably male or cobra intended (that't me talking). I buy mine on Black Friday so you get a smokin deal. Each entry gets a number. Once Ginny draws a number we keep in order. When your number is drawn you have a choice of a wrapped (disguised) gift to open or pick one someone else has already chosen or opened. Maximum hand change is 3 then out of play.
Fun comments by all.
