Greenville has a small station and no checked baggage any more. The one restroom (with a broken lock) is open when the sole Crescent comes through at about 5AM southbound (always seems to be on time) and 11PM northbound (but always seems to be 2 hours late). There is a ton of parking and the fact that it is an NS crew change point means there are people around even at those late hours so one feels safe even though the area is not well lit. There are no signs telling one where sleeper or coach passengers should board and no agent there to help any more. Tons of free parking and a $20 Uber ride to the airport means one can conveniently park there, Uber to airport to fly out then return by train at lest cost than parking at the airport. An all-night clean, bright QT gas station with tons of cheap snacks and better hot food than Amtrak's cafe is a 15 minute (.7 mile) walk or a quick(?) ride (over multiple speed bumps). No car rental places are nearby and not open at that hour anyway. For those going to the mountains (Asheville, Hendersonville), it's about 45 minute to 1 1/4 hour ride but that's only useful if someone is coming to pick you up. There is a local bus stop just a few blocks away. 6:15AM is over an hour wait for the first bus and 7:30PM is way early for the last one. Taxis can be called but they are likely to be the typical not-well-regulated ones with dirty cars, unknown pricing with irregular use of the meter and not reliable.
