For those of you who have been to the gems show. Can you tell me what to expect? how long to be there? how much should I budget (DH said I can go but leave the debit card at home - only with cash)? any tips, advice or warnings? I''m so excited that there will be one here in October! yippee.. I know its a bit early, but I was excited that I wanted to get others input and plan on just stashing away some $$ for it. TIA
