Ive read up on the public transportation from the airport and I’ve seen some mixed reviews. Anyone here taken it? Is it sketch?
As a solo traveler, I've done it a bunch, and I'll just say this - with a family, I wouldn't do it.
Less that it's sketchy, more that it's an absolute slog-and-a-half (2.5 hours), especially during either rush hour. The 460 bus is a local through Norwalk, and it's more than an hour through that section alone. It's miserable. Comparatively speaking, the whole trip
can feel "sketchy", but that really depends on your tolerance - like, if the idea of spending 90 minutes on a MARTA bus gives you hives, you might not enjoy it,
especially during rush hour. (The 460 is pretty nice late-morning or early afternoon, but, again, it's such a slog.)
You shouldn't have a problem getting direct flights from ATL to either LAX, BUR, or SNA. LAX will be the cheapest by far, but then it comes with the inconvenience of getting to Anaheim. With a party of five - if you
have to go through LAX, I would just hire a vehicle, even just an Uber/Lyft.
(If not the for the size of your party, I might suggest an alternate public transportation route, which would be the FlyAway bus to Union, then either Metrolink or Amtrak to ARTIC Anaheim, then Uber/Lyft to the hotel. But with a party of five, you're almost at the cost of an Uber/Lyft from LAX at that point, and the train trip is still about two hours.)
For the most part, I'd suggest what most folks here are saying - fly into SNA and take an Uber/Lyft. (I've done public transportation between SNA and DLR before, and it's also not awesome, mainly because there's not a direct route, so it turns a relatively quick trip into 60-90 minutes with at least one transfer.)
One wildcard possibility if you wanted to explore more of Los Angeles - I often fly into LAX and spend a night or two doing things around L.A. (ie, Universal), then (eventually) take the train from Union to Anaheim. From DLR, I'll go home via either SNA or LGB. (Side note: the LGB options for ATL aren't great, so I'd stick to SNA in that case, but LGB is another great option in/out of DLR.)
