Does anyone know when you should preorder?
preorder a month before your trip/weeks/or days before?
is there an expiration date?
I've been hearing rumors that there were expiration dates

TIA

Just wondering because my sister is going in 45 days and this is her 1st time going with her kids and she is not obsessed with disney like me so she doesn't know TOO many things...TIA!
