There were/are no Gold packages available?
I don't know. I was more concerned with getting the best seats the moment the presale started. I am not sure if you can do anything after the tickets have been purchased. I just sent that question directly to the folks at the casino.
Hmmm....well I hope it works out for you. I bought a meet and greet for my daughter and myself, she wanted that as a graduation gift. I hope you can do the same for your wife and daughter. Wish I had some help for you!
