MCO

Possibly an unusual question...but here we go.
We're flying to MCO in November, and a few days later I'm flying my partners family out to join us as a big surprise. Here's my question, we'll travel to the airport for some obsecure ticketing issue, where would be the best place for me to enter (while the other half waits with the car) to collect them and then 'appear'?
