Orlando airport is a busy airport. At any airport I try to always use the cell phone lot. The person picking up can wait there until the passenger calls and then be picked up curbside. No charge for waiting in the cell phone lots. The cab is also a good idea. I had never thought of that. There will be easy access to cabs by following the signs or asking.
You will enjoy Rainbow's End. There is also a nice cafe to eat near there but I can't remember the name of it.
