It was my first time buying kings dominion passes ...

It was my first time buying kings dominion passes for me and my family. Everything was fine till we decide to go after labor day I gold and 2 silver for the surprise they scan my daughters and it says expired. Very bad don't even notify or anything that the silver was no good after labor day very upseting.had to pay 40 dollars to get in for the silver.the supervisor there couldnt even do anything very bad.and still paying for the passes even if they expired with out notice. Will not be going back to kings dominion.
