My daughter is 2 years old so we were not planning on buying her a park ticket. It is my understanding that you need a ticket to get a fastpass. Does that mean I can't get a fastpass for my daughter unless I buy her a ticket? Thanks for the help!
You will not need a fastpass for your daughter. Just give the CM at the fastpass line your FP and you will have no problems. We have done this on our last 3 trips with no incident.
My son was two the first year we went and I was worried about fastpass too. They don't need them. As long as you have yours and you tell the CM they're under 3 it fine.
