Tralika,
If you go to Sun-n-fun.org and look around to buy tickets / buy camping / etc, you will see a discounted price for "members of aviation organization" and EAA as well as AOPA and twenty more qualify for a discounted price
Hope to see you there

ps, if going to show up and buy tickets at the entrance, I'd suggest that you have your eaa membership card in your pocket or on your phone.
Cheers!
