A tale of caution going through MCO security unless things have changed (doubt it though)
In early 2010 a group of us were traveling together Mom, Dad, Aunt, Sis, Bro, SIL, Niece, Nephew, DD age 2, DD age 4 ( turned 5 on our first full day at WDW), DH and Myself. Somehow Aunt, Sis, Bro, SIL, Niece and Nephew ended up in one line and the rest of us in another. The plan was to have My parents go through security first then send 5 year old through to Grandma while I kept 2 year old from taking off and DH took the carseat off the luggage rack. DH would go through security in order to put the carseat back on the luggage rack and secure it really quick while 2 year old went through security and then I would follow.
Here comes the snafu
Mom and Dad both having had double knee surgery plus Dad having a metal rod in his arm well you can guess set off the security alarm. They had to go and sit in a waiting area. 5 year old goes through security and my mom goes to the door of the little glass room to have her barely 5 year old granddaughter stand right there. Sit down, that child needs to be else where. Meanwhile DH and I are landside and both my mom and I are begging them to let her just stand right near the door and my mom on the other side. No absolutely not. My mom hollars from the door at my sister to come back and help. My sister and Aunt were together so they step to the side and my aunt stays with both their carry on luggage while my sister runs back to take my daughter until DH can get through. By then 2 year old is crying so my sister stayed and held her while DH finished getting her carseat set on the luggage rack.
The really funny or annoying thing is we were told by a TSA agent at our local airport that if there is an adult and you are sending adult child, adult child, adult through even if the adult needs additional screening they can still have the child with them until the other adult gets through security. We were also told that because my parents would need additional screening they should go through first.
Due to our having a 7:20 AM flight which by the number of internationals on DME I am guessing there are a lot of international departures at that time we had a DME departure time of 4 AM from the resort ( thank you sister for this one I have discovered there are later flights and trust me they will be utilized) we had plenty of time to get through security and to the gate ( where we sat and waited, and waited, and for a change of pace waited some more) we would have been fine sending DH through and then me followed by both girls and my parents. We also would have been better off having my aunt and sister go through the side with us due to the complications instead of ending up being split. I am guessing since my brother and SIL fly quite a bit going to various Nascar races and stuff so they are more used to going through so they went through the frequent traveler line instead of the family one like we did.
