I live in LA and want to spend a couple of days in a city I've never been to. Good public transport is big plus but I'll use Lyft if I have to. I like museums, libraries, public parks, historical sites, and I'm kind of a sports bro so I'd like to catch a baseball or soccer game. Probably take a week in April. So far I'm leaning towards NYC, Chicago, or New Orleans.
Nola public transit is good, but not as good as NYC or Chicago. The hardest part is getting from the airport to downtown. No trains, your only options are cars/taxis/ubers or a 90 min bus ride.
Once you are downtown, it's pretty good. St Charles trolly alone does a pretty good job connecting neighborhoods, and most of the popular districts are pretty walkable
