I actually was told by the station agent at Kissimmee that Amtrak does not sell Lakeland-Tampa or Tampa-Lakeland at all. I went to buy a round trip Kissimmee-Tampa-Kissimmee, just to ride down, have a drink, go in a taxi in Tampa to lunch somewhere, then come back to Kissimmee. The intent was 91 from Kissimmee at 11:11am arriving Tampa 12:55pm. Then return on 92 from Tampa at 5:20pm arriving Kissimmee 6:38pm. She advised me of the risk in buying this ticket (which of course I already knew) because 91 runs way late, way often, and I could actually miss the return of 92 out of Tampa if 91 was severely late. I decided not to buy the routing, and purchased an Orlando-New York trip instead. I happened to check later on, and sure enough, if I had taken the trip on that date, I would have been stranded at Tampa, because 91 was about nine hours late, and 92 was on time.
