Chamblee Station has been my most frequently-used station (since it's my closest one). I've found no fault in it, and the only thing I find funny about it is literally every time I come to the station to catch the next train, as I'm pulling into a parking spot, there's the train arriving! If one is traveling at peak times during the week, though, it shouldn't be a problem, as they're there about every ten minutes, and then generally every 15-20-ish minutes depending on the day.
In mentioning the parking, the spaces are tight, so one probably should not commute with a Yukon or an Excursion (though it's stereotypically probable that people who would be driving such vehicles wouldn't care much about using public transportation). There is ample parking, though, with three lots on either side of the station. One cannot leave one's vehicle at the station overnight, though (or, one shouldn't; at the very least, there's a less-than-24-hours guideline).
The station website (http://www.itsmarta.com/Chamblee.aspx) does say one can park there for $8 a day, but I've seen no evidence they've made the facility for it.
Being a fairly-used station, there are a few MARTA buses that meet at the station: the 19, 33, 47, 103, 126 (my personal favorite, but my bias is I can about literally leave my doorstep, catch this bus, and take it to the station), and 132. Also, having stared 4/24/2017, Gwinnett County Transit routes 101, 102, and 103 have stops at Chamblee Station, which is wonderful for those who want Gwinnett County access.
My favorite thing is having a basic, direct route to the airport, which takes about half an hour to reach, including station stops and pauses. The station may be lacking in some facilities (no long-term parking, no restrooms, and no RideStore), but it is a gateway to the wider MARTA and GCT network that really allows one -- especially with the challenges numbers of people have faced since the I-85 challenges arose -- to get where one might need to go without the hassle of heaps of traffic. read more
