There is no signage for the taxi stand. Jonathan, a Celebrity crew member stationed at the terminal exit door did not know either. There are buses parked directly outside the exit advertising $10 pp to the airport.
We found the taxi line. It is to the right when you exit the front door, right around the corner, out of sight.
We got in our taxi at 10:04 am. Our fare for the taxi minivan is $45 to get to TPA
