Flight
Rent car or ride share to hotel or accommodations. Take shuttle bus to car rental location and hail ride share from there. (It will be much faster!)
Hotel
We got a 20% discount on a block of rooms here, Downtown hotel rates are very high because of some kind of convention going on the same weekend. We'll be staying here in Koreatown which isn't too far from the Venue.
Train
Little Tokyo/Arts District Station Walk south on Alameda, two blocks, to E 4th Place (10min). For those arriving early Metro can be used to explore DTLA, Korea Town, Arts District, Little Tokyo neighborhoods and beyond.
