we went in Aug and used the vouchers for 3 adults. We also had 2 children with us, and our deposit ($30, don't ask me how the deposit was only 30, but it was) paid for kids' meal and tip. I'm sure you've read it around here, but the vouchers aren'a good deal for kids' meals, so maybe the way we did it would work for you.
Have a great time, Cindy's was just magical for the 6 yr old little girl we took!
