For those that don't know, Uber can no longer pick up at OIA. They agreed to stop pickups in a recent agreement with the City of Orlando.
Also, the insurance provided by Uber has not been found to be legal in Florida. For some reason no one is mentioning that, but it's true. Some drivers who drive for Uber have their own commercial insurance that is legal, but you won't know if the driver has commercial insurance until they arrive to pick you up.
I know taxis can be a pain, but using Uber in Florida is more of a risk than you might think. It might be OK in New York or San Francisco, but in Florida the laws and insurance have not caught up yet.
