The walk in Tampa isn't long but it is somewhat crazy. There is only one gate in terminal F that you come off the jetway and under the floor with the gate and they snake you around the bowels of the airport down to customs.
Last time I used it I was coming back from LGW
. It was nice to be one of the few that didn't have to go the "non-american" line or whatever its called.
